Abstract

We present simulation results for supercontinuum generation using As₂S₃ chalcogenide photonic crystal fibers. We found that more than 25% of input power can be shifted into the region between 3μm and 5μm using a pump wavelength of 2μm with a peak power of 1kW and an FWHM of 500fs. The broad dispersion profile and high nonlinearity in As₂S₃ chalcogenide glass are essential for this application.
