Nonlinear optical signal processing by ultrafast Raman pulses in silicon-on-insulator rib waveguides is theoretically investigated in this paper. Stimulated Raman scattering, twophoton absorption, free carrier dispersion, self- and cross-phase-modulation-induced by Kerr effect, walk-off, group velocity dispersion, pump depletion, self-steeping, and polarization coupling are taken into account by a very general modeling under subpicosecond regime. Raman amplification, multiwavelength conversion, soliton formation, and pulse compression are presented and discussed. Finally, some simulations for generation of higher order Stokes pulses in mid-IR region are given.

Abstract
Nonlinear optical signal processing by ultrafast Raman pulses in silicon-on-insulator rib waveguides is theoretically investigated in this paper. Stimulated Raman scattering, twophoton absorption, free carrier dispersion, self- and cross-phase-modulation-induced by Kerr effect, walk-off, group velocity dispersion, pump depletion, self-steeping, and polarization coupling are taken into account by a very general modeling under subpicosecond regime. Raman amplification, multiwavelength conversion, soliton formation, and pulse compression are presented and discussed. Finally, some simulations for generation of higher order Stokes pulses in mid-IR region are given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
