Description
We report the simulation of ultrafast pulse evolution along the silicon germanium waveguide. Pulse evolutions of 205 fs duration and 2.35 kW peak power at 4.15 μm propagating along a 7 cm long silicon germanium on silicon air-clad waveguide were simulated by solving the generalised nonlinear Schrödinger equation using the fourth order Runge Kutta in the interaction picture method. Coherent supercontinuum covering more than one octave from 2.61 – 8.16 μm (relating to a bandwidth of 5.54 μm) at -30 dB is achieved. The simulated spectra fully spans the 4 – 8 μm spectral region comprising of molecular fingerprints for most hazardous and greenhouse gases making it attractive for gas absorption spectroscopy applications.
