9. Integrated optics Bragg grating ring resonators with Q-factor on gigascale

Author

Campanella, C. E., Ciminelli, C., and Armenise, M. N.

Subjects
Physics - Optics
Abstract

In this paper we propose a new optical ring resonator with a very high Q-factor, to be used as a basic element in a wide range of physics and engineering applications. We theoretically demonstrate that in large size conventional ring resonators, a value of the Q-factor higher than 109 is achievable by exploiting the band-edge resonances in a waveguiding long period Bragg grating closed loop, excited through a bus waveguide. The dispersion introduced by the Bragg grating is responsible for a reduction in the band edge resonance linewidth, which is inversely proportional to the square of the number of periods of the grating, thus allowing the overall Q-factor to be enhanced. Numerical results show a substantial improvement in the Q-factor, giving a number of order of magnitude higher than that of a conventional large size ring resonator., Comment: The paper has been withdrawn due to the need for further investigation

20. Recent advances in miniaturized optical gyroscopes

Abstract

Low-cost chip-scale optoelectronic gyroscopes having a resolution ≤ 10°/h and a good reliability also in harsh environments could have a strong impact on the medium/high performance gyro market, which is currently dominated by well-established bulk optical angular velocity sensors. The R&D activity aiming at the demonstration of those miniaturized sensors is crucial for aerospace/defense industry, and thus it is attracting an increasing research effort and notably funds. In this paper the recent technological advances on the compact optoelectronic gyroscopes with low weight and high energy saving are reviewed. Attention is paid to both the so-called gyroscope-on-a-chip, which is a novel sensor, at the infantile stage, whose optical components are monolithically integrated on a single indium phosphide chip, and to a new ultra-high Q ring resonator for gyro applications with a configuration including a 1D photonic crystal in the resonant path. The emerging field of the gyros based on passive ring cavities, which have already shown performance comparable with that of optical fiber gyros, is also discussed.

33. Theoretical investigation on the scale factor of a triple ring cavity to be used in frequency sensitive resonant gyroscopes

Subjects

Abstract

In this paper we study a multi-ring resonant structure including three evanescently coupled ring resonators (named triple ring resonator, TRR), with different ring radii and coupling coefficients, and coupled to two bus waveguides. The potential application of a TRR as a rotation sensor is analyzed and its advantages over a single ring resonator (SRR) under rotation conditions are also highlighted. When the coupled rings have different size and their inter-ring coupling coefficients are lower than the ring-bus coupling coefficients, the resonance frequency difference between two counter-propagating beams induced by rotation is enhanced with respect to that of a single ring resonator (SRR) with the same footprint. The scale factor of the rotating TRR, which depends on the structural parameters (i.e. inter-ring and ring-bus coupling coefficients, lengths of the rings, overall propagation loss within the rings), is up to 1.88 times the value of the scale factor of a SRR, which depends only on the ring radius, by assuming that the waveguide structure in both configurations is the same. This promising numerical achievement results in a reduction of the sensor footprint of about two times, with respect to a single ring with the same scale factor. The results obtained may be useful to define new configurations of frequency sensitive optical gyros in low-loss technology, having a small volume. In fact, by properly choosing the structural parameters, the spectral response of the TRR is forced to assume a shape more sensitive to the resonant frequency shift due to the rotation with respect to that one of a SRR.

36. Optical modelling of a Si-based DBR laser source using a nanocrystal Si-sensitized Er-doped silica rib waveguide in the C-band

Abstract

The availability of reliable silicon-based laser sources is at the basis of the integration of photonic and microelectronic devices on a single chip with consequent development of wavelength division multiplexing telecommunication systems. A high efficiency Si-based laser source with good stability at room temperature would encourage and push the large scale of integration of electronic and photonic devices within a single chip. Several techniques have been proposed for generating light with an internal quantum efficiency some order of magnitude greater than that typical of silicon (10−6) by using either electrical or optical pumping. Among them we mention the improvement of some fabrication process steps, reduction of the channels of non-radiative recombination, quantum confinement, the use of silicon nanocrystals (Si-ncs) incorporated in a silica matrix. This last technique is used in combination with Er3+ doping to generate light emission around 1500 nm in silicon, since Er-doped Si-ncs behave as electron-hole pairs trap, and the presence of Er shifts the emission peak to around 1500 nm. In this paper we have pointed out the optical model of a Si-based DBR laser including a Si-ncs Er-doped SiO2 rib waveguide, working at a wavelength in C-band. In particular, after a brief description of the structural and optical properties of the silicon crystals, we report on the model and design of the Er:Si-nc/SiO2 rib waveguide, of the optical cavity and of the Bragg mirrors.

42. Simulation of the photodynamics of azobenzene on its first excited state: Comparison of full multiple spawning and surface hopping treatments.

Abstract

We have studied the cis→trans and trans→cis photoisomerization of azobenzene after n→π* excitation using the full multiple spawning (FMS) method for nonadiabatic wave-packet dynamics with potential-energy surfaces and couplings determined “on the fly” from a reparametrized multiconfigurational semiempirical method. We compare the FMS results with a previous direct dynamics treatment using the same potential-energy surfaces and couplings, but with the nonadiabatic dynamics modeled using a semiclassical surface hopping (SH) method. We concentrate on the dynamical effects that determine the photoisomerization quantum yields, namely, the rate of radiationless electronic relaxation and the character of motion along the reaction coordinate. The quantal and semiclassical results are in good general agreement, confirming our previous analysis of the photodynamics. The SH method slightly overestimates the rate of excited state decay, leading in this case to lower quantum yields. [ABSTRACT FROM AUTHOR]

44. Low loss waveguides for standardized InP integration processes

Author

D'Agostino, D., Carnicella, G., Ciminelli, C., Ambrosius, H.P.M.M., Smit, M.K., Garcia-Blanco, S.M., Boller, K.J., Sefunc, M.A., Geuzebroek, D., Photonic Integration, and NanoLab@TU/e

Abstract

InP generic processes allow monolithic integration of sources, passive elements and detectors on a common p-n doped layerstack. The passive loss can be greatly reduced by formation of local p-n junctions by means of Zn-Diffusion or regrowth. The attainable loss is experimentally derived from spiral ring resonators, coupled to a waveguide via multimode interference. By folding the ring into a spiral we obtain circumferences up to 73 mm, with a footprint of 2.4 mm x 3.6 mm. We measure a quality factor of 1.2 million and extinction ratio of 9.7 dB, implying a loss below 0.4 dB/cm
