Développement de nouvelles matrices vitreuses pour la fonctionnalisation de fibres optiques par l’exploitation de la technologie Poudre

Abstract : The main part of optical fibers used in the fields of optical sources and sensors are called 'functionalised', i.e. they have new properties, due to their nature and/or structure, compared to standard fibers. To do this, we will use 'Powder' technology for the realization of optical fiber using properties of original vitreous glasses developed during this thesis. Three families of optical fibers will be studied in order to demonstrate the great potential of this association, materials - technology. The first exploit the structuring of the cladding with two vitreous glass rods (Panda type) doped or not with copper oxide. The study of this fiber is done from the synthesis of the material up to the test of this fiber as a sensor. The second fiber leads us to design a novel optical glass matrix, to define the optimal composition and decline form of an optical fiber including the glass for the core. Finally, the optical fiber manufacturing process is used to produce optical fiber with glass-ceramic core, i.e. starting from a vitreous matrix specially developed for this application happen to grow the nano-structures in the core of the fiber and obtain a novel fiber family.
