    We numerically demonstrated that the generation of 1.4-10 μm mid-infrared supercontinuum from highly nonlinear Ge11.5As24Se64.5 based photonic crystal fiber chalcogenide glass. This ultra-broadband supercontinuum achieved for 150 mm long photonic crystal fiber pumped with 85 femto-second laser pulses operated at 3.1 μm and peak power pulse is 5 kW. A broad and flat dispersion profile of Ge11.5As24Se64.5 PCF associated with the extreme nonlinearity and generate hyper broadband supercontinuum. Raman gain of Ge11.5As24Se64.5 glass is four times higher to fused silica and As2Se3 glass and Raman frequency shift for the Ge11.5As24Se64.5 glass is ≈ 7.1 THz.
