Abstract
In this paper a detailed investigation of Four Wave Mixing in Silicon-on-Insulator
optical waveguides is carried out under pulsed regime. A number of nonlinear
effects, such as two photon absorption, free carrier absorption, self and
cross phase modulation are considered in the analysis, as well as walk-off,
group velocity dispersion and third order dispersion. The interesting influence
of pulsewidth on the space-time evolution of both signal and idler pulses
is presented. Optimized phase matching conditions are found to achieve very
efficient wavelength conversion in parametric amplification, considering both
degenerate and non degenerate processes. Finally, waveguide parameters are
optimized for rib and membrane SOI waveguides.
