Abstract: International audience; A micro-resonator based on porous silicon ridge waveguides is implemented by a large scale standard photolithography process to obtain a low cost and sensitive sensor based on volume detection principle instead of the evanescent one usually used. The porous nature of the ridge waveguides allows the target molecules to be infiltrated in the core and to be detected by direct interaction with the propagated light. Racetrack resonator with radius of 100 µm and a coupling length of 70 µm is optically characterized for the volume detection of different concentrations of glucose. A high sensitivity of 560 nm/RIU is reached with only one micro-resonator and a limit of detection of 8.10-5 RIU, equivalent to a glucose concentration of 0.7 g/L, is obtained.

Abstract: International audience; In this paper, we demonstrate a new method to obtain a low gap between the access waveguide and the racetrack cavity of a micro-resonator based on porous silica material and using standard photolithographic process. The photolithographic process is first carried out on porous silicon layers to obtain porous silicon ridge waveguides that constitutes the racetrack micro-resonator. Then the full oxidation of the micro-resonator is performed. Because of the volume expansion of silicon that occurs during its full oxidation, the gap is reduced. Lower gaps and then lower coupling distances can be obtained using a low cost photolithographic process compared to e-beam technology. This original method proposed in this paper allows to improve the miniaturization of such porous silica micro-resonators which is of great interest for integrated optical biosensor application.

Abstract: International audience; The design of Porous Silicon (PSi) integrated micro-resonators is studied for both surface sensing and homogeneous sensing at 1550 nm to optimize the sensors' sensitivity and Limit of Detection (LOD) as a function of the porosity, dimensions and propagation losses of PSi ridge waveguides. A model for estimating the different contributions to the losses of PSi waveguide as a function of the dimensions and the porosity is then developed to allow calculation of the performance of the sensor. Low refractive index difference and high porosities mean that higher sensor performance can be obtained due to the reduction of surface scattering losses as the waveguide dimensions become larger. The sensitivity and limit of detection calculated in this paper for optimized dimensions and porosities of PSi ridge waveguides are respectively 0.04 nm/(pg.mm-2) and 0.5 pg.mm-2 for Bovin Serum Albumin (BSA) molecules surface sensing which are higher than the state of the art. For homogeneous detection, a promising sensitivity of 800 nm/RIU, higher than the sensitivities that can be currently obtained with one micro-resonator, has been estimated. A limit of detection of 1.2.10-4 RIU, which is within the range of state of the art of micro-resonator (MR) based biological sensors, has also been calculated for homogeneous detection. These promising results obtained by the optimization of the porosity and the ridge waveguide dimensions with respect to optical losses reinforce the attraction of PSi for integrated optical sensing application. Highlights:-The performances of micro-ring resonator biological sensor based on porous silicon waveguides are calculated in terms of sensitivity and limit of detection as a function of porosity and waveguide dimensions.-A micro-resonator is designed for both surface and homogeneous sensing by taking into account the optical losses.-A comparison of the performances of micro-resonator sensors for both surface and homogenous detection highlights the interest of porous silicon waveguides having optimized porosities and dimensions, in obtaining the best limit of detection and sensitivity that are currently possible to reach with only one micro-resonator.

Abstract: International audience; Few-mode optical fibers (FMFs) are useful for many applications such as space-division-multiplexing (SDM), high laser power generation and transport, dispersion compensation, etc. The emergence of SDM induces considerable requirements in term of FMF characterization (chromatic dispersion, birefringence, modal content, bending losses). All LP modes of a FMF can be simultaneously characterized using phase-sensitive Optical Low-Coherence Interferometry (OLCI). The differential modal group delay and absolute chromatic dispersion values of each mode are retrieved from a single measurement without spatial mode transformers.

Abstract: International audience; Porous silicon (PSi) is material which physical and optical properties have been widely studied for biological sensors. Indeed, the wide internal surface of PSi, as well as its biocompatibility have significant advantages for use in the fields of sensors. Moreover, integrated micro-resonators (MRs), by their geometry and operating principle, allow to fabricate very sensitive and miniaturized sensors. The PSi MR is destined to be used as an optical transducer for domains using the sensing and analysis of specific molecules such as health, food industries and security. The porous nature of the ridge waveguide allows the target molecules to be infiltrated in the guiding layer and being detected by direct interaction with the propagated light. This volume detection will significantly enhance the sensor sensitivity and will allow a lowest limit of detection compared to those obtained by using usual MRs based on evanescent wave detection. Integrated racetrack MR made from partially oxidized PSi ridge waveguides are implemented using an electrochemical etching method of silicon substrate, followed by a thermal oxidation and then by a standard photolithography process. The obtained MRs are structurally and optically characterized. The work has demonstrated experimentally the possibility of sensing concentrations of glucose with a partially oxidized porous silicon MR as transducer. A sensitivity of 560 nm/RIU is obtained which is currently the highest measured value.

Abstract: International audience; The future technology migration in access networks compels the development of key innovative transmitters operating at 10 Gb/s around 1550 nm and capable of transmitting data in extended reach passive optical networks (>60 km). A laser modulated directly appears to be a low cost and a simple solution to address these needs. However, the extinction ratio and the distance of transmission are limited by frequency chirping inherent to high bit rate modulation at 1550 nm. In this letter, we demonstrate the monolithic integration of a directly modulated lasers and a ring resonator (RR) and show the possibility to engineer the RR with specific frequency modulation efficiency. The ring is used as an optical eye reshaper, which enables the increase of the extinction ratio above 9 dB. Transmissions up to 65 km with 5.8 dBm of modulated optical power coupled into the fiber are demonstrated, proving the feasibility of our transmitter for the next generation passive optical network stage 2

Abstract: International audience; Racetrack micro-resonator (MR), made from partially or totally oxidized porous silicon (PS) ridge waveguides fabricated with standard photolithography process, is reported. The design and the technological process are described including a study of waveguide dimensions that provide single mode propagation. Scanning electronic microscopy observations and optical characterizations clearly show that the MR based on PS ridge waveguides has been well implemented. As the MRs will be used for sensing application, we also present a preliminary theoretical study of the porous MRs sensitivity. A very promising theoretical sensitivity around 1200 nm/RIU (Refractive Index Unit) has been calculated for such porous racetrack MR.

Abstract: In order to take advantage of the very high nonlinear susceptibility of conjugated polymer materials, Poly(3- AlkylThiophene)s, P3AT, were synthesized in the laboratory. The physical, thermomechanical and linear optical proper- ties of synthesized P3AT have been investigated and the first experimental attempts at creating nonlinear optical waveguides and determining their characteristics are presented. After synthesizing P3AT, the relationships between poly- mer chain characteristics and mechanical properties are investigated to see if the polymer is suitable for optical waveguide process technology. We also examine the optical attenuation of the synthesized material, a crucial factor in anticipating the relative opacity of the future component. For the first time we present the absorption spectrum of 3-Octylthiophene molecules in the Near Infra-Red (NIR) region that suggests optical losses for the material are about 0.6 dB.cm -1 at 1550 nm. Next we examined several waveguide structures such as ridge, buried and Strip Loaded WaveGuides (SLWG) based on P3AT material. For the buried waveguides, we have observed the signal transmission and in our opinion the low opti- cal transmission of P3AT ridge and SLWG could be attributed to extrinsic losses (mainly scattering) due to both the re- maining insoluble products in the polymer and to the poor adhesion between optical layers.

Abstract: International audience; The time domain coupled-mode theory (CMT) is applied to the analysis of the dynamic of third-order optical nonlinear effects in high-finesse whispering-gallery-mode (WGM) resonators. We show that this model is well adapted to the analysis of cavity-ringdown spectroscopy signal under modal-coupling due to Rayleigh backscattering in linear and nonlinear regimes. The experiments are carried out in silica WGM microspheres. Considering thermal and Kerr effects, CMT simulations are in good agreement, with experimental results for input power up to about 1 mW. For well-known optical materials such as silica, this experimental data analysis method can be used to measure the quality factor, the coupling regime, and the mode volume of high-finesse WGM. Furthermore, this technique could be developed to infer linear and nonlinear properties of high-finesse coated WGM microspheres.

Abstract: International audience; A new combination of porous silicon and polymer optical waveguides is investigated for two different designs of Vernier effect based sensors for the surface detection of Bovine Serum Albumin molecules (BSA). The hybrid structures studied consist of two cascaded micro-resonators for one and a micro-resonator cascaded with a Mach-Zehnder for the other. Because of its high specific surface and bio-compatibility, we use porous silicon to implement the waveguides in the sensing part of the sensor into which BSA molecules are grafted. Polymer waveguides are then used for the reference part of the sensor because of their low optical losses. We consider the opto-geometric parameters of both waveguides for single mode propagation. Finally, optimized designs, taking into account standard experimental wavelength shift measurement limitation are presented for both structures. We demonstrate a theoretical Limit Of Detection (LOD) of 0.019 pg.mm-2 and a sensitivity of 12.5 nm/(pg.mm-2) with these hybrid sensors. To our knowledge, these values are lower by a factor of 8 for the LOD and higher, by a factor of 200 for the sensitivity, as compared to state of the art Vernier effect biosensors.

Abstract: International audience; The performance of a ring-resonator based passive wavelength router, suitable for optical networking at chip level, is evaluated through BER measurements in single channel 10 Gbit/s and 3-channel 10 Gbit/s WDM configurations. As the routing path involves a different number of routing elements, depending on the wavelength used for the propagating signal, the performance of three output ports with respect to a specified input one are experimentally evaluated and discussed. Measurements show that low rejection on the filter elements due to fabrication issues mostly affect the channel on the through path with respect to the dropped ones.

Abstract: International audience; We propose a new solution for modal decomposition in multimode fibers, based on a spectral and spatial imaging technique. The appearance of spurious modes in the spectral and spatial processing of the images at the output of the fiber under test when it has more than two modes is demonstrated theoretically. The new method, which allows us to identify spurious modes, is more accurate, simpler, and faster than previously reported methods. For demonstration, measurements in a standard step-index multimode fiber and a small-core microstructured fiber are carried out successfully.

Abstract: Chalcogenide glasses are known for their high non-linear optical properties (100 – 1000 times as high as the non linearity of silica glass). To enhance the non-linear properties, As-Se suspended-core fibers were manufactured. First, high-purity glasses were elaborated and moulded to obtain high-quality preforms. After drawing, the diameter of the suspended core can be less than 2 µm, which corresponds to a non-linear parameter γ of nearly 30 000 W−1·km−1. Self-phase modulation, four-wave mixing and Raman effects can be observed and studied in those fibers at the telecom wavelengths.

Abstract: comID: MC2.2; International audience; Chalcogenide glasses are based on a mixture of chalcogen elements (Sulphur, Selenium and Tellurium) and other elements such as Arsenic, Germanium, Antimony or Gallium. Compared to silica glasses, they offer several distinctive optical properties such as their transmission window which extends far into the infrared spectral region (up to 25μm for telluride glasses). Chalcogenide glasses also exhibit an extremely high nonlinear index coefficient n2 that can be two or three orders of magnitude greater than in silica at 1.55 μm. These nonlinear properties can be further enhanced by drawing these glasses into Chalcogenide Photonic Crystal Fibers (CPCF) due to the possibility of designing such fibers with a very small core diameter. Since 2004, PERFOS and the laboratory "Glass and Ceramics" of Rennes University (EVC) have worked together to develop CPCFs and are currently investigating a new method to fabricate chalcogenides preforms based on the glass casting process.

Abstract: conference 7717 " Optical Modelling and Design ", session 6 " Wave Optics II " [7717-30]; International audience; Both theoretical and experimental analysis of a new efficient method to measure the number and type of modes propagating in optical fibers are presented. This consists in measuring the intensity of the near field image at the end of a fiber while scanning the wavelength with a laser source signal. Modes are extracted from Fourier transformation of the spectral data at each point (x,y) of the images. A novel technique which is referred to as scalar product technique is implemented in order to reconfirm real modes and exclude spurious modes. The technique is based on the orthogonality of different modes. A standard multimode fiber has been measured to verify the technique. Three real modes LP01, LP11, and LP02 are discovered and reconfirmed by the orthogonality with the minimum values of the scalar products. One spurious mode, which comes from the dependence of the power of the laser source on the wavelength, is thus excluded as it is not orthogonal either to the LP11 mode or the LP02 mode.

Abstract: We propose and demonstrate two methods for modal decomposition in multi-mode fibres. Linearly polarized modes propagating in a slightly multi-mode fibre are easily retrieved from intensity measurements at the fibre output surface. The first method is an improvement of the so-called spectrally and spatially imaging technique, which is limited to largemode- area optical fibers. The second method is a new, simpler and faster solution for the characterization of any kind of optical fibre, thus attractive in comparison to previously reported methods, which are cumbersome, time-consuming and/or limited to large-more-area fibres. Different kinds of multi-mode optical fibres are characterized. A large-modearea photonic-bandgap fibre, a photonic-crystal small-core non-linear fibre, and a standard index-stepped multi-mode fibre are characterized successfully.

Abstract: Topic " Optoelectronic Materials and Devices ", conference 7212 " Optical Components and Materials VI ", session 4 " Passive Fibers " [7212-14]; International audience; In this work, we review recent progress on the realization of chalcogenides Photonic Crystal Fibers (PCFs). We present the fabrication of chalcogenide PCFs with a solid core for three different glass compositions containing a variety of chalcogens. We show that the Stack and Draw technique currently used for silica PCFs can be problematic in the case of chalcogenides glasses. We present correct PCF design enables a significant improvement of final fiber losses. We obtained a lowest attenuation of 3 dB/m at 1.55 µm, of 4.5 dB/m at 3.39 µm and 6 dB/m at 9.3 µm. We also present experimental demonstration of self phase modulation spectral broadening around 1,55 µm. Moreover, we investigate the Brillouin and Raman scattering properties of a GeSbS PCF.

Abstract: special issue « Fiber Optic Research in France » (Part II of III); International audience; In this paper we present a review of different micro-lenses we have developed at the end of single-mode fibers for improving optical coupling efficiency in communication systems. These micro-lenses find their applications in laser-diodes or integrated waveguides to single mode fibers, fiber to detector coupling, or fiber-to-fiber interconnecting. More generally, the applications concern active or passive components to single mode fiber coupling. Three kinds of micro-lenses are considered whose fabrication process has been designed to be very simple and low cost. Some of them are produced by companies in Lannion such as IDIL Fibers Optiques.

Abstract: conference 6996 " Silicon Photonics and Photonic Integrated Circuits ", poster session, [6996-63], http://spie.org/x24034.xml; International audience; Polymers are increasingly attractive for the creation of optical integrated circuits particularly owing to a high thermo-optical coefficient (-10-4 °C-1) which allows to design optical functions tunable according to temperature. For example, tunable filters or multiplexers are attractive in telecom applications for bringing broadband services to subscribers. Moreover, the large available range of refractive index, leads to large scale of integration, lowering the fabrication costs and could be an alternative solution to semiconductor or inorganic dielectric technologies. In this work, optical functions were created using standard photolithography and Reactive Ion Etching (RIE). Photolithography was used with particular conditions to improve pattern resolution. Firstly, the details of making optical polymer waveguides and wavelength micro-ring based filters are given. Optical loss measurements of waveguides and optical characterisation of micro-ring resonators are also shown for which the results are in agreement with the modelling. Secondly, the same micro-ring resonators were observed with the temperature change and we noticed that the variation of resonance wavelength is about 0.2 nm.°C-1. This is just what is needed for the creation of tunable filters or multiplexers without electrical high power, considering the very small size of the component.

Abstract: International audience; We present a novel and simple method to measure both the value of the second-order dispersion coefficient and the nonlinear coefficient in optical fibers. This method is based on the higher-order soliton-effect pulse compression phenomenon and is valid for dispersion values greater than 0.5 ps/km/nm. A non-zero dispersion-shifted fiber, a standard single-mode fiber and a highly-dispersive highly-nonlinear fiber have been measured using this method.
