Dispositifs a bande photonique interdite pour des applications de textiles photoniques et capteurs plasmoniques.

摘要

This document presents the main achievements of our Master's activities. The submission by papers include two of the numerous publications on various subjects originated by our work. Despite the apparent mismatch of the presented topics, both projects rely on similar technologies. The common goal is to demonstrate new fields of application for photonic bandgap based waveguides.;At first, implementation of Bragg fibers made of polymer was oriented towards photonic textiles industry; pieces of fabric with integrated optical functionalities. Our original proposition features the visually appealing signature or our Bragg fibers. In fact, they can take evolutive appearance by proper control over active and passive illumination, revealing the broad spectral possibilities offered by their microstructure. Among our experimental realizations figure additive synthesis of colors based on two different approaches, successful integration of fibers to a silk matrix and optical measurement of deformation, namely. Manipulations performed in a tightly controlled laboratory environment confirmed the rich potential of our Bragg fibers in photonic textiles related applications.;Our second study concerned improvement of detecting capabilities of plasmonic sensors by means of various photonic crystal waveguides. When applied to plasmonic based refractometry applications, conventional waveguides do not offer convincing alternative to existing free space systems. Our proposition consists on achieving the delicate phase matching condition required for sensing principle operation by exploiting the flexible design of photonic bandgap waveguides. Competitive performance of our proposition was verified with the use of simulation tools, but experimental confirmation of our models validity still remains to be done. Preliminary results are nevertheless encouraging.
