Paper Abstract

Based on a three-band model, a polarization-dependent pulsed four-wave mixing (FWM) model which can be used to analyze the optical sampling process in semiconductor optical amplifier (SOA) is presented. The polarization-dependent characteristics and cross-polarization modulation (XPolM) of pump, probe and conjugate pulses are investigated in detail. The maximum sampling efficiency occurs, when pump and probe pulses are linearly co-polarized and parallel to the TE axis. When the pump, probe pulses with initial linear polarization states interacting in an SOA, their polarization states do not just rotate and the conjugate pulse is not just linearly polarized but with complicated polarization states during the propagation along the length of SOA.
