Abstract

We present results of numerical simulations of a supercontinuum generation (SCG) in a Ge_11:5As₂₄Se_64:5 chalcogenide rectangular waveguide with air as an upper cladding and the lower cladding is magnesium fluoride. A broadband infrared 1.3-3.0 μm SCG could be achieved by pumping with femtosecond pulses in the two zero dispersion wavelengths. The effect of chirp on SCG spectrum has been also investigated. The simulation shows a significant SCG spectral flatness in the mid-infrared range with positive frequency chirp input pulses.
