Abstract

We present simulation results for supercontinuum generation using tapered As₂S₃ chalcogenide photonic crystal fibers (PCFs). We demonstrate that an increased soliton self-frequency shift can be achieved using a tapered PCF. There is an optimal tapered PCF, which yields an additional 0.4μm shift to longer wavelengths relative to the shift that is obtained in an untapered PCF, leading to an increase in the bandwidth from 2.5μm to 3.6μm. However, the ratio of the output power in the region between 3 and 5μm to the input power decreases in a tapered fiber because of the increased fiber leakage loss.
