This paper describes an approximate analysis of Raman generation in silicon-on-insulator (SOI) rib waveguide with DBR/F-P resonator and an integrated p-i-n (PIN) junction, taking into account spatial field distribution and nonlinear effects involved in silicon. These effects comprise especially, stimulated Raman scattering (SRS), free-carrier absorption (FCA), degenerate two-photon absorption (i.e. the pump-pump TPA) and non-degenerate two-photon absorption (i.e. the pump-Stokes TPA and the Stokes-pump TPA). Applying the reverse biased PIN junction allows to reduce the nonlinear optical losses due to TPA-induced FCA. The model is based on the semiclassical approach and an energy theorem. In threshold analysis of steady-state Raman laser operation, an analytical formula relating input pump power to the system parameters is obtained. It allows analyzing the influence of all physical and geometrical parameters on the threshold pump power. The analysis of the above threshold operation is based on the exact energy conservation relation, in which the approximated pump and Stokes field distributions are used. The Stokes field distributions are approximated by that existing at the threshold, whereas the approximate pump field distributions are obtained by integrating the equations for the pump signal using the linear (threshold) pump field distributions and the threshold Stokes field distributions. We obtain an approximate, semi-analytical expression related the Raman output power to the pump power and system parameters.
