We found that 25% of the input power of a 2 mum wavelength 1 kW peak-power source can be shifted into the region between 3-5 mum using an As2S3-based chalcogenide PCF. Tapering increases the output at wavelengths above 4 mum.
We show the Raman response function and dispersion curve for a chalcogenide fiber. We then model and reproduce the experimental bandwidth of IR supercontinuum generation using a chalcogenide PCF.
