Model optimization of SOA used in ultra-high bit rate OTDM demultiplexer

Abstract

The ultrafast femtosecond gain and phase dynamics of semiconductor optical amplifier (SOA) are investigated in this work. Acomprehensive model is developed which takes in to account interband transition, intraband transition SHB, CH, TPA, polarization state of control pulse and data . the model is used to extract the femotosecond switching dynamics of the SOA under different operating condition such as injection current ,control pulse power ,control pulse polarization ,SOA length and TPA.
