SOA modeling for advanced optical modulation formats
Abstract
The numerical modeling of semiconductor optical amplifiers (SOA) being able to simulate all of nonlinear effects of the SOA, particularly FWM effect, is presented. This model is integrated into a co-simulation platform to perform a simulation at a system level. A CO-OFDM transmission link and EVM measurement are used to study the impact of SOA and its relation to the number of subcarriers and phase-amplitude coupling.
