title = "Analysis of femtosecond self-polarization modulation in semiconductor optical amplifier",
abstract = "Based on a three-band model, a new theoretical model is derived to describe the self-polarization modulation (SPoIM) effect in semiconductor optical amplifier (SOA) on femtosecond time-scale. In the case of SPoIM, the phase difference between the TE and the TM modes is created by the signal itself and results in changes of polarization states of the signal. Numerical experiments are carried out to analyze the gain and the signal induced phase shift when an ultrashort optical pulse injected into a tensile strained SOA. The higher injected power can induce a larger phase shift. The polarization-dependent effect has much more influences on strong optical pulses.",
