A micro-ring space-time control circuit is proposed for micro-supercapacitor application. The center micro-ring circuit consists of sandwiched titanium dioxide (TiO2) thin film. The input light fed into the circuit via the input port is of 1.55 µm wavelength. The input space source is multiplexed with time at the add port to form the space-time function. A whispering-gallery mode is formed using suitable parameters, which results from the nonlinearity effect induced by the small rings at the sides of the center micro-ring. The light that excites the gold metal surface leads to electron cloud oscillations that form the electron density, which can be transported via wireless connection by employing the whispering-gallery mode or via cable connection.

The biased plasmonic circuit is proposed using a Panda-ring infinitesimal space–time function control. The circuit has two small rings alongside the main microring. The small rings act as phase modulators inducing the nonlinearity effect in the circuit. The gold grating at the center microring induces plasmonic polaritons resulting in plasmonic wave oscillations and the Bragg wavelength (plasma frequency). By using the suitable parameters, the whispering gallery mode (WGM) is formed at the center ring, where the small change of light optical path difference is compensated and resonant. The coupling side ring radii $${R}_{L}$$ - $${R}_{R}$$ → 0 is generated, where the unified space–time function is obtained. The saturation uncertainty space–time function known as a singularity is formed, which can be applied for fully biased plasmonic circuit characteristics. The circuit is fed by the input light with 1.50 µm center wavelength, where the input power varied from 1 to 10 mW. The bright soliton with a wavelength of 1.50 µm can move both back and forward (biased) on the time axis by the three different modulated Gaussian pulses of 0.60 µm, 1.10 µm, and 1.30 µm, where the full biased of the 1st space to the 2nd various spaces in terms of wavelengths is achieved.

The microring circuit is designed to form the upstream and downstream quantum communications. There are one space and two-time functions applied to form the transmission. A circuit consists of 3 microring resonators, where there are three processes of each transmission. Firstly, the space function pulse (soliton) fed into the system via the main ring input port. The whispering gallery mode (WGM) is generated at the center ring with suitable parameters. The dipole oscillation is formed by the coupling between plasmonic wave and gold grating, which will change in the dipole oscillation frequency inducing the change in the plasmonic sensor. The flip-flop signals obtained from the bright and dark soliton via the throughput and drop ports can apply for the transmission clock signals. Secondly, the quantum codes formed by a time-energy function input into the system via a silicon ring, which induced the four-wave mixing induced by the coherent light in a GaAsInP ring, can be identified and the quantum bits(qubits) formed by the polarized signal orientation. The quantum information is multiplexed into the system. Thirdly, the carrier time function will input via the add port main ring. By using the resonant condition, the multiplexed signals of those processes will transmit via either WGM or throughput port for wireless or cable transmission, respectively. The downstream process is processed the same way as the upstream, where the multiplexer is placed by the de-multiplexer. By varying the input power, the manipulation result has shown the potential realistic application for quantum and telepathic communications.

The Sagnac interferometer consists of four microring probes integrated into a Sagnac loop. Each of the microring probes is embedded with the silver bars to form the plasmonic wave oscillation. The polarized light of 1.50µm wavelength is input into the interferometer, which is polarized randomly into upstream and downstream directions. The polarization outputs can be controlled by the space-time input at the Sagnac port. Electrons are trapped and oscillated by the whispering gallery modes (WGMs), where the plasmonic antennas are established and applied for wireless fidelity (WiFi) and light fidelity (LiFi) sensing probes, respectively. Four antenna gains are 2.59dB, 0.93dB, 1.75dB, and 1.16dB, respectively. In manipulation, the sensing probe electron densities are changed by input source power variation. When the electron cloud is excited by the microscopic medium, where the change in electron density is obtained and reflected to the required parameters. Such a system is a novel device that can be applied for brain-device interfering with the dual-mode sensing probes. The obtained WGM sensors are 1.35µm-2, 0.90µm-2, 0.97µm-2 and, 0.81µm-2, respectively. The WGMs behave as a four-point probe for the electron cloud distributed sensors, where the electron cloud sensitivities of 2.31prads-1mm3 (electrons)-1, 2.27prads-1mm3 (electrons)-1, 2.22prads-1mm3(electrons)-1, 2.38prads-1mm3(electrons)-1 are obtained, respectively.

A negative entropic system formed by a close successive polariton filtering within a modified optical add–drop filter is proposed. The device ends are embedded by the gold gratings and TiO2 materials, in which the close successive polariton filtering can be formed. The selected light source is input into the system via the input port. There is no light energy injected and left into and from the system after the initial input, which can be configured as the adiabatic-like system. Polariton forms by the coupling between the intense optical field and the optical dipole generated by the gold grating. The suitable reflector (TiO2 material) lengths are applied to all device ends, from which only a small amount of the polariton output energy can be transmitted and measured at the add port output. By using the Optiwave and MATLAB programs, the polariton outputs regarding wavelength, time and frequency of the stopping states can be found and plotted. The relative polariton negentropic values of the red- and blueshifted signals are also calculated. The maximum relative negentropic value of 6.8 × 1015 m2 s−2 is obtained. The possible hibernation and quantum consciousness interpretation using the proposed system are also discussed.

Polaritonic signal processing model and manipulation using a microring successive filtering circuit are proposed. The polariton signals are generated by the coherent light within the microring embedded a gold nanograting island, from which the successive filtering of the polariton signals within the designed on-chip circuit is manipulated by adjusting the device end reflection coefficients. The almost closed system of the two-level system of polaritons is formed, where there are initially two oscillation frequencies called the Rabi frequencies, the ground an excited state respectively.

We propose a new concept of the nonlinear effect called the Kerr-Vernier effect by using cascaded Si-ChG microring circuits. The circuit is simulated for two materials of different refractive indices which results in phase difference in propagating light and hence observed in the output signal. By varying the input power into the system, the Vernier effects in terms of the Kerr-Vernier effects are seen. In application, the comparative results of the two-channel outputs are used to form the phase sensors, while the self-calibration between the two-channel outputs can be performed. The change in wavelength at the whispering gallery mode of 8 nm is achieved when the applied input power was fixed at 10 mW. A sensitivity of ∼120 µm W-1 is obtained for this proposed sensor.

3D interference fringe pattern recognition using a plasmonic sensing circuit is proposed. The plasmonic sensing in the form of a panda ring comprises an embedded gold grating at the microring center. WGM (whispering gallery mode) is observed at the microring center with suitable parameters. The dark soliton of 1.50 µm wavelength excites the gold grating which leads to electron cloud oscillation and forms the electron densities where the trapped electrons inside the silicon microring are transported via wireless connection using WGM and cable connection. The spin down $$\left| \downarrow \right\rangle\left( {\left| 1 \right\rangle } \right)$$ and spin up $$\left| \uparrow \right\rangle\left( {\left| 0 \right\rangle } \right)$$ result from the electron cloud oscillation. By using the changes in gold lengths, the excited electron pattern recognition can be manipulated, where the values “0” and “1” are useful for pattern recognition. The fringe patterns of the plasmonic interferometric sensor are recorded, which means that the novel 3D pattern recognition can be possibly implemented and used in many applications. Therefore, the plasmonic sensing circuit can be used to form the quantum code, quantum encryption, quantum sensor, and pattern recognition.

The creation of the Internet of Things (IoT), along with the latest developments in wearable technology, has provided new opportunities in human activity recognition (HAR). The modern smartwatch offers the potential for data from sensors to be relayed to novel IoT platforms, which allow the constant tracking and monitoring of human movement and behavior. Recently, traditional activity recognition techniques have done research in advance by choosing machine learning methods such as artificial neural network, decision tree, support vector machine, and naive Bayes. Nonetheless, these conventional machine learning techniques depend inevitably on heuristically handcrafted feature extraction, in which human domain knowledge is normally limited. This work proposes a hybrid deep learning model called CNN-LSTM that employed Long Short-Term Memory (LSTM) networks for activity recognition with the Convolution Neural Network (CNN). The study makes use of HAR involving smartwatches to categorize hand movements. Using the study based on the Wireless Sensor Data Mining (WISDM) public benchmark dataset, the recognition abilities of the deep learning model can be accessed. The accuracy, precision, recall, and F-measure statistics are employed using the evaluation metrics to assess the recognition abilities of LSTM models proposed. The findings indicate that this hybrid deep learning model offers better performance than its rivals, where the achievement of 96.2% accuracy, while the f-measure is 96.3%, is obtained. The results show that the proposed CNN-LSTM can support an improvement of the performance of activity recognition.

A silicon microring circuit embedded gold film with unique characteristics is proposed for Hall effect, current, and temperature sensing applications. The microring circuit is operated by the input polarized laser sources, in which the space-time distortion control can be employed. A gold film is embedded at the microring center. The whispering gallery mode (WGM) is generated and applied for plasmonic waves, from which the trapped electron cloud oscillation is formed. Through the input port, the input polarized light of 1.55 μm wavelength fed into the space-time control circuit. Spin-up |↑〉(|0〉) and spin-down |↓〉(|1〉) of polarized electrons result when the gold film is illuminated by the WGM. The electric current passing through the gold film generates a magnetic field (B), which is orthogonal to the electric field.

In this paper, the ultra‐wideband source for light fidelity (LiFi) and high‐density 3D imaging applications is proposed. The system consists of an add‐drop multiplexer. The center ring is formed by the Chalcogenide glass (ChG), which is coupled with two GaAsInP/P side rings. The nonlinear effect within the side rings (phase modulators) is induced in the central ring. The superposition of light signals from side rings generates wider wavelength band, which makes the original input. The output is the set of squeezed light pulses known as whispering gallery mode (WGM) which is generated at the center of the system. Three different input sources are investigated, where the simulated results are comparatively plotted and discussed. The results show that the wavelength of 1.30 μm is the best input source. The output wavelengths band is ranged from 0.7‐3.1 μm, which is suitable for LiFi source and high‐density 3D imaging applications.

The simulations have shown that a combination of 7 roll-off bands with the maximum spectral widths or bandwidths of ∼6.09 µm or ∼7.63 THz can be obtained.

We have proposed a model of polariton generation, which is normally generated by the dipole and the strong coupling field interaction. This system consists of a gold grating embedded on the plasmonic island, which is embedded at the center of the nonlinear microring resonator, which is known as a panda-ring resonator. The strong coupling between the plasmonic waves and the grating can be formed by the whispering gallery mode (WGM) of light within a Panda-ring resonator, in which the output is a dipole-like particle known as a polariton and seen at the system output. By varying the energy of high-intensity laser pulse in the system and gold granting a strong field is generated at the output. A dipole is formed by a pair of the grating signals, where one propagates in the opposite direction of the other. By using suitable parameters, dipole-like signals can be generated. Theoretical formulation is performed for a two-level system and polariton oscillation frequency i.e., the Rabi frequency is plotted. The obtained ground and excited state frequencies of this two-level system are 187.86 and 198.20 THz, respectively.

An on-chip-scale, up-down link conversion circuit for electro-optic signals to use in a light fidelity network application is proposed. A system consisting of a loop microring resonator (known as a Panda-ring resonator), is coupled inline to the input of a Mach–Zehnder interferometer (MZI). When the light from that source is input into the system, a fraction of the power is coupled inline through successive pumping and then circulated within the system. By using the most appropriate device parameters, the whispering gallery mode (WGM) of the light, with the inline successive pumping condition, is generated at the resonance condition. The transmitted signals are a combination of the comb and WGM signals and are obtained at the MZI output. The simulation results obtained have shown that a maximum power of 300 mW is achieved from the device. A comb signal, over the spectral band from 1.350–1.750 µm is obtained, with the center wavelength at 1.55 µm. The results show an up-downlink switching speed of is ~ 20 fs is also obtained.

This work presents an optical switching model that the tweezer probe uses for manually switching the controlled by an external switch, in which the upward and downward switching can be operated and simultaneously switched. By using the microring resonator incorporated with the two non-linear phase modulators, the optical tweezer can be generated and the switching probes controlled. The switching time with the table force of ~2 fs is obtained. The tweezer force and torque are calculated and interpreted for molecule trapping and injecting from and to the trapping and the target surfaces. The relative forces and torques are calculated and plotted. In applications, the specific forces and torques can be controlled to perform the appropriate trapping and injecting. The switching time depends on the external switching module, which may be electronically controlled.

We have proposed the simple method of the squeezed light generation in the modified microring resonator, which is known as the microring conjugate mirror (MCM). When the monochromatic light is input into the MCM, the general form of the squeezed coherent states for a quantum harmonic oscillator can be generated by controlling the additional two side rings, which are the phase modulators. By using the graphical method called the Optiwave program, the coherent squeezed states of coherent light within an MCM can be obtained and interpreted as the amplitude, phase, quadrature and photon number-squeezed states. This method has shown potentials for microring related device design, which can be used before practical applications.

We propose the remote charger model using the light fidelity (LiFi) transmission and integrate microring resonator circuit. It consists of the stacked layers of silicon-graphene-gold materials known as a plasmonic island placed at the center of the modified add-drop filter. The input light power from the remote LiFi can enter into the island via a silicon waveguide. The optimized input power is obtained by the coupled micro-lens on the silicon surface. The induced electron mobility generated in the gold layer by the interfacing layer between silicon-graphene. This is the reversed interaction of the whispering gallery mode light power of the microring system, in which the generated power is fed back into the microring circuit. The electron mobility is the required output and obtained at the device ports and characterized for the remote current source applications. The obtained calculation results have shown that the output current of ∼2.5 × 10−11 AW−1, with the gold height of 1.0 µm and the input power of 5.0 W is obtained at the output port, which is shown the potential application for a short range free pace remote charger.

This letter presents the use of a plasmonic sensing transducer on an embedded Mach–Zehnder interferometer (MZI) arm, allowing the sensing transducer to be formed through the stacked layers of the silicon–graphene–gold materials and embedded on an MZI arm with a gripping force to allow it to be used in sensing applications. The transduction process introduces an energy conversion between the input light and the excited electron mobility within the silicon and graphene layers. That way the electron drift velocity within the gold layer can drive the plasmonic wave group velocity induced through the interaction with the graphene layers, and consequently, the electron mobility in the gold layer increases. The driven electron mobility in the gold layer, caused by the plasmonic waves from graphene in the embedded sensing layers, will affect the electron output mobility, where the relative change in the phase of the light in the silicon can be seen at the output port of the MZI. To optimize the key parameters of such a system (especially input optical power and dimensions of the gold layer), simulations are performed at various input optical powers and the results are graphically represented. A maximum sensitivity of ~ $2\times {10}^{-14}$ mV−1s−1 in electron mobility sensing is obtained through these simulations, designed to optimize the performance characteristics of the proposed sensor.

A conventional Michelson interferometer is modified and used to form the various types of interferometers. The basic system consists of a conventional Michelson interferometer with silicon-graphene-gold embedded between layers on the ports. When light from the monochromatic source is input into the system via the input port (silicon waveguide), the change in optical path difference (OPD) of light traveling in the stacked layers introduces the change in the optical phase, which affects to the electron mean free path within the gold layer, induces the change in the overall electron mobility can be seen by the interferometer output visibility. Further plasmonic waves are introduced on the graphene thin film and the electron mobility occurred within the gold layer, in which the light-electron energy conversion in terms of the electron mobility can be observed, the gold layer length is 100 nm. The measurement resolution in terms of the OPD of ∼50 nm is achieved. In applications, the outputs of the drop port device of the modified Michelson interferometer can be arranged by the different detectors, where the polarized light outputs, the photon outputs, the electron spin outputs can be obtained by the interference fringe visibility, mobility visibility and the spin up-down splitting output energies. The modified Michelson interferometer theory and the detection schemes are given in details.

The electro-optic power pumping system model using the inline successive technique within the modified add-drop filter is proposed. A pumping system consists of a closed loop Panda ring resonator, from which the optical power is coupled inline into the system. By controlling the two side phase modulators, the whispering gallery mode (WGM) is generated by the amplitude-squeezed light within the modified add-drop filter. By using the proposed circuits, the low current can be applied into the system via a gold layer connection, from which the amplified output current can be obtained at the throughput port, which can be functioned as the electronic operational amplifier (op-amp). In application, the WGM output is the amplified signal that can be used for the up (down) link in free space communication network called light fidelity (LiFi). The electro-optic signals conversion can be performed by the stacked layers of silicon–graphene–gold materials. The results obtained have shown that large gain is obtained at the WGM output, which is ~ 5 × $$10^{ - 6}\; {\text{cm}}^{2} \;({\text{V}}\;{\text{sW}})^{ - 1}$$ , when the pumping saturation time is ~ 2 fs. It concludes the suitability of our proposed model for light fidelity, LiFi up-down link conversion.

In this article, we have proposed the plasmonic interferometry concept and analytical details given. By using the conventional optical interferometry, which can be simply calculated by using the relationship between the electric field and electron mobility, the interference mobility visibility (fringe visibility) can be observed. The surface plasmons in the sensing arm of the Michelson interferometer is constructed by the stacked layers of the silicon-graphene-gold, allows to characterize the spatial resolution of light beams in terms of the electron mobility down to 100-nm scales, with measured coherence lengths as low as ∼100 nm for an incident wavelength of 1550 nm. We have demonstrated a compact plasmonic interferometer that can apply to the electron mean free paths measurement, from which the precise determination can be used for the high-resolution mean free path measurement and sensing applications. This system provides the practical simulation device parameters that can be fabricated and tested by the experimental platform.

The plasmonic electronic component consists of the stacked layers of silicon–graphene–gold materials can be integrated with the driven group velocity system, which is nonlinear microring resonator. This determines the suitable driven velocity in controlling the side ring phase modulators. In such a case, the proposed system can give the advantage of the greater switching speed and the hybrid function between electronic and light signals. The obtained I–V output characteristics of the transmitted results have shown that the proposed circuit can function to be the electronic devices with very high stability.

By using the monochromatic input light source, the electro-optic signals can be generated and functioned as the step up and down conversion by mean of the on-chip optoelectronic transformer. The step up and down of the electro-optic related power conversions can be obtained via the input and drop port connections. The results obtained have shown that the flexible up and down electro-optic conversion ratios of 1: 5 and 10:1 for the step up and down conversions, respectively. The uses light source wavelength source was centered at 800 nm, where the conversion stability of 1600 fs is noted. The linearity trend of the conversion stability is confirmed.

A system of radio over free space optic (RoFSO) system using the multi-optical carriers has been generated by the microring resonators integrating an add/drop filter. These obtained carriers have shown sufficiently stable for propagating in free space channels while experiencing very low dispersion. Moreover, this technique is appropriated for higher capacity that can be serviced in a system of wavelength-division multiplexing (WDM) RoFSO, where there are 16 carriers created, where each carrier has 12.5 GHz free spectral range (FSR) and 220 MHz full-width at half-maximum (FWHM) and 8 orthogonal frequency division multiplex (OFDM) signals, then they separately modulated with 8 out of these 16 carriers. After the modulation, by utilizing an free space optic (FSO) antenna, all carriers have the optical multiplexing and transmission to a FSO channel. On the receiver side, the demultiplexing is performed and finally the performance of the system subsequently is analyzed by calculation of the constellation diagram and error vector magnitude (EVM).

We have proposed the convincing electro-optic circuit for long life-time electron mobility emission. Light a monochromatic source is utilized as input into the circuit via the input port and trapped within the plasmonic island. It is a formed-like capacitor structure formed by the silicon-graphene-gold materials which are stacked layers. All circuit port ends have added the TiO2 to form the reflectors. By selecting the suitable parameters, the fraction of the output power emission can be controlled at the add port, from which it can be successively pumping and trapped(stored) within the plasmonic island. The system energy saturation can be released by squeezing light behavior, therefore, the system is always balanced due to the successive pumping process. The results obtained of the single cell(circuit) have shown that the charging time and discharging times of the nano-capacitor-like of ∼2 to 3 s and 1000 h are achieved. This can be applied to long life mobility emission(discharge) of the capacity-like device. The mobility storage time within the island is 14,000 h, with the electron mobility of ∼3.0 × 10−7 cm2 Vs−1 is obtained.

In this paper, a micro-stereo sensor is proposed using two-identical Panda-ring resonators, which are coupled by jointed drop ports. When light from the identical coherent sources is fed into the system via the input ports, the coupling outputs are obtained at the drop port at the resonant condition. These are mixed signals in the form of stereo signals. By using different input power between the right and left systems, the phase difference generated by the Kerr-Effect in the non-linear medium leads to the shift in the coupling outputs. The shift in the center wavelength is the primary measurement of interest along with coupling crosstalk signals that are also visible at the output. The measurement self-calibration of the two channels is confirmed by the mixed channel signals. In the manipulation, the crosstalk signals can be used to interpret the cross-communication of bio-cells. The crosstalk results have shown the optical crosstalks of ∼2.0 and ∼2.5 dB are calculated and obtained, respectively. The stereo sensor sensitivity of ∼5.70 nmW−1is noted.

In this work, the use of a micro-conjugate mirror that can produce the 3D image incident probe and display is proposed. By using the proposed system together with the concept of naked-eye 3D imaging, a pixel and a large volume pixel of a 3D image can be created and displayed as naked-eye perception, which is valuable for the large volume naked-eye 3D imaging applications. In operation, a naked-eye 3D image that has a large pixel volume will be constructed by using the MIMO micro-ring conjugate mirror system. Thereafter, these 3D images, formed by the first micro-ring conjugate mirror system, can be transmitted through an optical link to a short distance away and reconstructed via the recovery conjugate mirror at the other end of the transmission. The image transmission is performed by the Fourier integral in MATLAB and compares to the Opti-wave program results. The Fourier convolution is also included for the large volume image transmission. The simulation is used for the manipulation, where the array of a micro-conjugate mirror system is designed and simulated for the MIMO system. The naked-eye 3D imaging is confirmed by the concept of the conjugate mirror in both the input and output images, in terms of the four-wave mixing (FWM), which is discussed and interpreted.

The design of the microsensor system for biosensors using the plasmonic island is proposed. The sensor head is formed by the stacked layers of silicon-graphene-gold materials. The dual-mode operations of the sensor can be performed using the relationship of the changes between the electron mobility and optical phase, where the exciting environment can be light intensity (phase), electrical transient, heat, pressure, flavour and smoke, The change in light phase (intensity) in silicon and conductivity (mobility) in gold layers cause change in the output measurands. The design and simulation interpretation of the sensor is presented. The sensor manipulation using the MCM arrangement is simulated and interpreted for biosensor applications 3D imaging can also be applied to the MCM function, where the 3D in situ sensor function is possible.

Three different wavelength light sources are coupled to microring circulator via modified add-drop multiplexers, from which the multiplexed signals of them can be formed at the plasmonic islands and used as the distributed sensor nodes. The change in the wavelength due to the external environment will affect the refractive index of the sensing material and hence shift in each wavelength will be seen. Measurements are recorded as the shift in a spectrum (Δλ) by changing the input power and a relationship is obtained between the change in input power and shift in the output spectrum for 1.10, 1.30 and 1.55 μm wavelengths. This is the micro-scale device that can be used for bio-cell content distributed sensors, in which the three different aspects of sensor mechanism can be employed.

The new optical communication bandwidths (wavelength bands) using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. The Gaussian input pulses, for instance, when the input pulses of the common lasers with center wavelengths from 400 to 1500 nm are used, the required output wavelength bands can be obtained by controlling the coupling coefficients of the add/drop filter. Results obtained have shown that more available wavelength bands from the different center wavelengths can be generated, which can be used to form new dense wavelength division multiplexing bands. The novelty of the work is that the expansion of communication bands, especially, when the center wavelength is at 1300 nm can be obtained by using a common laser pulse, whereas the amplified and non-dispersive light source can be formed.

We propose a novel system of multi optical trapping tool using a bright soliton pulses propagating within the add/drop optical filter system. The multiplexing signals with different wavelengths of the bright solition are controlled and amplified within the system. The dynamic behavior of bright soliton interaction is analyzed and described. The signal is controlled and tuned to be an optical probe which can be configured as the multi optical tweezers. By using some suitable parameters, we found that the tweezers widths in add/drop at the drop ports are about 18 nm is achieved. Therefore, the generated multi optical tweezers can be amplified within the design system. In application, the optical tweezers train can be trapped light/atom, which can be transmitted and recovered by using the proposed system.

We propose a new system of an extremely narrow light pulse generation for optical microscopy applications using a nonlinear ring resonator system. The system consists of one nano and three micro-optical ring resonators, which can be used to generate the 50 fm (10 −15 m) optical spectral width at the broad wavelength spectrum. By using a soliton pulse with a pulse width of 50 ps, peak power of 1 W, center wavelength at 550 nm, and after the soliton pulse is launched into the first ring device, the chaotic pulses are generated within the first ring. The chaotic filtering behaviors are performed by using the second and the third ring devices, whereas the extremely short pulse, i.e. narrow spectral width, can be generated by using the extended nano-ring device. The broad spectrum of the harmonic waves is generated and filtered, which is of use in optical tomography. Results obtained have shown that the generation of the broad spectrum of short pulse with width 100 fm and peak power 60 mW is achieved. The possibility of using such a system for nondestructive bio-cells microscopy, for visualizing bio-cells and for bio-cells tomography is also discussed in detail.
