A Detailed Circuit Model for Semiconductor Optical Amplifier Incorporating Thermal Effects

Abstract

A detailed circuit model for semiconductor optical amplifier, which incorporates thermal and spectral behavior, is reported. The rate equations of semiconductor optical amplifier form the basis for the equivalent circuit development. The circuit is simulated for static and dynamic conditions and its performance as amplifier, modulator and detector are evaluated. Further, thermal effects on the characteristics of SOA are determined. The SOA performance is studied in the temperature range of 283-343 K and the results are found to agree well with the literature.
