Abstract :
Raman gain, two photon absorption, free carrier dispersion, self and cross phase modulation induced by Kerr effect are investigated theoretically in silicon-on-insulator waveguides. The influence of the rib waveguide sizes on the time-space evolution of the pump pulse and Stokes wave is presented. Finally, the application of the nonlinear effects in silicon to realise an all-optical switch is proposed.
