Résumé

An original way to obtain fibers with special chromatic dispersion and single-​mode behavior is to consider microstructured optical fibers (MOFs)​. These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. In this study, the first all-​solid all-​chalcogenide MOFs exhibiting photonic bandgap transmission have been achieved and optically characterized. The fibers are made of an As38Se62 matrix, with inclusions of Te20As30Se50 glass that shows a higher refractive index (n = 2.9)​. In those fibers, several transmission bands have been obsd. in mid IR depending on the geometry. In addn., for the first time, propagation by photonic bandgap effect in an all-​chalcogenide MOF has been obsd. at 3.39 μm, 9.3 μm, and 10.6 μm. The numerical simulations based on the optogeometric properties of the fibers agree well with the exptl. characterizations.
