Nonlinear polarization rotation induced by ultrashort optical pulses in a semiconductor optical ampl

    We use a new rate-equation model for the propagation of sub-picosecond polarized optical pulses in a semiconductor
    optical amplifier (SOA). This model is based on the decomposition of the polarized optical field into TE and TM
    components that interact via the gain saturation, and accounts for two-photon absorption, free-carrier absorption, selfand
    cross-phase modulation, carrier heating, and spectral and spatial hole burning. For the first time, using our model,
    we have obtained numerical results for the nonlinear polarization rotation in pump–probe experiments with 200 fs
    pulses. These results are in good agreement with reported experimental measurements.
