Modelling of Different Types of SOA Characteristics
Abstract
An investigation of gain, optical power, and amplified spontaneous emission (ASE) noise characteristics of different types of semiconductor optical amplifier (SOA) operating in the conventional (C-) band is carried out. The types of SOAs include linear, nonlinear and in-line SOA that are customized in a wideband travelling wave (TW) SOA configuration through OptiSystem software. These SOAs are further simulated in MATLAB using a numerical steady-state model to determine and evaluate their performance. The results showed that the linear SOA has the most ideal and distinct characteristics, as compared to the nonlinear and in-line SOAs rendering it more suitable as gain medium in the multiwavelength fiber laser (MWFL) application.
