Chalcogenide Microstructured Fibers for Infrared Systems, Elaboration, Modelization, and Characterization

special issue " Fiber Optic Research in France " (Part III of III)International audienceChalcogenide fibers present numerous possible applications in the IR field. For many applications, single mode fibers must be obtained. An original way is the realization of microstructured optical fibers (MOFs) with solid core. These fibers present a broad range of optical properties thanks to the high number of freedom degrees of their geometrical structure. In this context, we have developed MOFs for near and mid IR transmission with different geometries and properties such as multimode or endless single-mode operation, small or large mode area fibers. We have also investigated numerically the main linear properties of such MOFs
