Coherent mid-infrared supercontinuum generation in tapered suspended-core AsSe fibers pumped by a few-optical-cycle Cr:ZnSe laser.

We report on efficient supercontinuum generation in tapered suspended-core $ {{\rm As}_{39}}{{\rm Se}_{61}} $AsSe fibers pumped by a femtosecond mode-locked Cr:ZnSe laser. The supercontinuum spectrum spans the mid-infrared spectral region from 1.4 to 4.

Broadband mid-IR chalcogenide fiber couplers.

We demonstrate a broadband AsS-based fiber coupler operating up to the 5.4 μm wavelength range developed by using a fused biconical tapering technique. During the manufacturing process, real-time data monitoring of the coupling ratio was at 2.
