Paper Abstract

The dispersion characteristics of Arsenic Trisulfide As2S3 chalcogenide glass were analyzed and a kind of As2S3 microstructured optical fiber was designed to shift the zero dispersion wavelength from longer than 4 μm to around 2 μm. The supercontinuum generation in the designed fiber with selected pump wavelengths and pulse durations were simulated through numerically solving the Generalized Nonlinear Schrödinger Equation. The results reveal that the broadest supercontinuum covering 1.1 μm to 5.5 μm can be obtained with pump laser with duration 150 fs centered at 2.0 μm which is slightly longer than the first zero dispersion wavelength. When the pump wavelength is around the zero dispersion wavelength apparent dispersive waves which are significant for spectral broadening can be observed.
