An array of 18 FBGs spectrally distributed over 70 nm was written in a polyimide-coated fiber, with a single uniform phase-mask, by applying strain on the fiber prior to exposition. This flexible method will be used to develop directional sensor for distributed sensing based on a hybrid glass-polymer multicore fiber.

We report the use of Interferometric Second Harmonic Generation (I-SHG) microscopy to eliminate imaging artifacts from SHG patterns. Boundaries between two regions of opposite polarities in periodically-poled lithium niobate (PPLN) and in muscle myosin are compared, and shown to produce respectively incoherent contributions to the SHG signal and artefactual interferences. I-SHG allows to remove those artifacts, which opens a great opportunity for a better characterization of SHG images of various materials, especially complex media like biological tissues.

Chalcogenide films are deposited by radio frequency (RF) magnetron sputtering on different cladding layers (thermally oxidized silicon and selenide-based materials). Ridge waveguides and micro-ring resonators are then processed using photolithography and dry etching techniques. Nonlinear effects from these devices (self-phase modulation and four-wave mixing) are experimentally demonstrated. From these results, a theoretical study is developed to design nonlinear photonic structures to demonstrate optical parametric oscillations, tunable microwave signal generation on optical carrier, supercontinuum generation or Brillouin scattering.

Praseodymium-doped selenide thin films are deposited by radio frequency (RF) magnetron sputtering on thermally oxidized silicon wafers. Ridge waveguides are then processed using photolithography and dry etching techniques. Under optical pumping at $1.55 mu mathrm {m}$, broadband guided midinfrared photoluminescence is recorded between 3.5 and $5.5 mu mathrm {m}$. Optical design confirmed that these active waveguides allow single-mode optical propagation at different absorption wavelengths of important environmental gases (CO2, CO, NO). Mid-Wave Infrared (MWIR) multimode interferometer (MMI)based demultiplexer are designed for multispecies gas sensing.

Due to long and diffraction-free interaction length and controllable dispersion, hollow-core photonic crystal fibers (HCPCFs), especially Kagome-lattice HCPCFs, can open the door to new possibilities in nonlinear optics in liquids and gases. We present a brief study on dispersion of noble-gas-filled HCPCFs and demonstrated how a desire zero dispersion wavelength and flattened dispersion can be tuned using core diameter and gas pressure in HCPCFs.
