Abstract

A rectangular photonic crystal fiber in GeSe₂-As₂Se₃-PbSe chalcogenide system has been numerically modeled for coherent mid-infrared supercontinuum generation.. The proposed design offers zero dispersion wavelength at 4100 nm for the optimized geometrical parameters. The nonlinear coefficient is found as high (206 W^-1.km^-1) corresponding to the effective mode area of 8.5 μm² against pump wavelength at 4.1 μm. The proposed fiber is expected to be a good candidate for the generation of coherent supercontinuum mid-infrared lasers sources.
