Abstract

We demonstrate numerically a possible generation of a mid-infrared (1-10 μm) supercontinuum, using highly nonlinear Ge11.5As24Se64.5-based photonic crystal fibres. This ultra-broadband supercontinuum is achieved with a 100 mm long photonic crystal fibre pumped using 85 fs laser pulses at 3.1 μm with the peak power 3 kW. A broad and flat dispersion profile of the Ge11.5As24Se64.5-based photonic crystal fibre combined with a high nonlinearity result in the hyper-broadband supercontinuum.
