Micro-resonators (MR) have become a key element for integrated optical sensors due to their integration capability and easy fabrication with low cost polymer materials. Nowadays, there is growing need on MRs as highly sensitive selective functions especially in the areas of food health. The context this work implement study micro-ring resonators devoted sensing applications. They are fabricated by processing SU8 core layer PMATRIFE lower cladding layer. refractive index polymers waveguide...

A new combination of porous silicon and polymer optical waveguides is investigated for two different designs Vernier effect based sensors the surface detection Bovine Serum Albumin (BSA) molecules. The hybrid structures studied consist cascaded micro-resonators one a micro-resonator with Mach-Zehnder other. Because its high specific bio-compatibility, we use to implement in sensing part sensor into which BSA molecules are grafted. Polymer then used reference because their low losses. We...
We demonstrate the interest of expanded beam microlenses (around 55 µm mode field diameter) to relax positioning tolerances and decrease reflectance in single fiber interconnexions. also point out micro-lenses very small diameter 2 µm) improve coupling efficiency specialty fibers integrated waveguides for non linear effects based functions sensors applications at a wavelength 1.55 µm.
The different biosensing strategies with microring resonators consist in quantifying the resonance shift under presence of biological or chemical agents. These lead to measurement a wavelength an output power variation correlated analyte concentration. design guidelines enhance sensitivity have been already studied and reviewed over past decade. However, very few studies published addressing ring resonator performance used as absorption micro-spectrometer, which can be explored colorimetric...
Research on sensors has experienced a noticeable development over the last decades especially in label free optical biosensors. However, compact without markers for rapid, reliable and inexpensive detection of various substances induce significant research new technological solutions. The context this work is sensor based easily integrated micro-resonator (MR) component optics, highly sensitive selective mainly areas health food. In work, we take advantage our previous studies filters...
This work presents a detailed modeling-based analysis of integrated micro-ring resonators used for absorption spectroscopy. Generally, sensors based on detect changes in the real part sensing medium refractive index, at critical coupling. In spectroscopy, however, are to measure imaginary index and most sensitive away from coupling, with separate maxima under- over-coupled regimes. this work, we present under-coupled regime, explaining relationships between sensitivity, mode confinement,...
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 optical characterizations clearly show MR based on PS has been well implemented. As MRs will be used for sensing application, we also present...
