Recent progress on the realization of chalcogenides Photonic CrystalFibers

摘要

In this work, we review recent progress on the realization of chalcogenides Photonic Crystal Fibers (PCFs). We presentthe fabrication of chalcogenide PCFs with a solid core for three different glass compositions containing a variety ofchalcogens. We show that the Stack and Draw technique currently used for silica PCFs can be problematic in the case ofchalcogenides glasses. We present correct PCF design enables a significant improvement of final fiber losses. Weobtained a lowest attenuation of 3 dB/m at 1.55 pm, of 4.5 dB/m at 3.39 um and 6 dB/m at 9.3 pm. We also presentexperimental demonstration of self phase modulation spectral broadening around 1,55 gm. Moreover, we investigate theBrillouin and Raman scattering properties of a GeSbS PCF.
