Stimulated Raman scattering, two-photon absorption, free-carrier dispersion, self-phase and cross-phase modulations induced by the Kerr effect, walk-off, pump depletion, and polarization coupling are investigated theoretically in silicon-oninsulator optical waveguides. The influence of submicrometerscale rib waveguide sizes on the time–space evolution of both pump and fundamental and higher order Stokes’ picosecond pulses is presented. Finally, the threshold conditions for higher order Stokes’ waves have been found and interpolated by a simple formula.
