Description
Summary:We rigorously investigated the mid-infrared supercontinuum generation in a multimode As Se chalcogenide photonic crystal fiber (PCF). We studied the impact of the intermodal nonlinear effects on the nonlinear propagation of the fundamental and high-order modes. By solving the multimode generalized nonlinear Schrödinger equation, we have predicted the generation of a very broadband supercontinuum in both polarizations of the fundamental mode spanning from 2 to 11 μm at -20  dB in only 5 cm PCF length. The proposed study confirms that the energy transfer occurs only between the optical degenerate modes when propagating in the multimode chalcogenide PCF in the mid-infrared region.
