Propagation non-linéaire d'impulsions femtosecondes dans une fibre optique à bande interdite à cœur solide
National audience; Nous décrivons une étude expérimentale et numérique de l'évolution non-linéaire d'impulsions ultrabrèves se propageant dans une fibre optique à bande interdite à coeur solide. Suivant le mécanisme de guidage employé, des dynamiques significativement différentes sont mises en évidence.
Chalcogenide microstructured optical fibers : from linear to nonlinear properties
International audience; In this talk, we review the linear properties of chalcogenide microstructured optical fibers (MOFs) of several types. We mainly focus our talk on mid-infrared applications of such fibers. We start with the general properties of solid core MOFs made of these high index glasses and compare them with the ones of silica. Then, we give some details concerning a solid core MOF made of TAS glass. Next, we describe the first guiding suspended chalcogenide MOF and explain how it was designed for supercontinuum generation in the mid-infrared. Both linear and nonlinear properties of As2S3 suspended core MOFs are also numerically studied. In the next part, We describe the design…
