In this Letter, we numerically simulate the generation of a 1–15 μm mid-infrared supercontinuum(SC) from a highly nonlinear Ge_(11.5)As24Se_(64.5)-based photonic crystal fiber(PCF). This ultra-broadband SC is achieved in a100 mm long PCF pumped using 85 fs laser pulses operated at 3.1 μm and a peak pulse power of 3 k W. The proposed design offers a flat dispersion profile with two zero dispersion wavelengths. This broad and flat dispersion profile of the Ge_(11.5)As24Se_(64.5)PCF, combined with the high nonlinearity(2474 W-1km-1), generates an ultra-broadband SC.
