Abstract
It is shown that chalcogenide double-clad fibers (Ch-DCFs) have large potential to realize the highly coherent mid-infrared (MIR) supercontinuum generation. We design the Ch-DCFs with flatter chromatic dispersion and smaller effective mode diameter than chalcogenide step index fibers in the MIR region. We numerically investigate MIR supercontinuum generation in designed Ch-DCFs. It is numerically demonstrated that highly coherent MIR supercontinuum extending from 3.3 to 10.4 μm in the Ch-DCFs can be generated by pumping with hyperbolic secant pulse at 6 μm, the peak power of 2 kW, and the full width at half maximum of 300 fs.
