We present simulation results for supercontinuum generation using As 2 S 3 chalcogenide photonic crystal fibers. We found that more than 25% of input power can be shifted into the region between 3 μm and 5 μm using a pump wavelength of 2 μm with a peak power of 1 kW and an FWHM of 500 fs. The broad dispersion profile and high nonlinearity in As 2 S 3 chalcogenide glass are essential for this application.
