Influence of SOA parameters on the nonlinear impairments experienced by QAM modulated signals

We propose an experimental method to tune SOA model parameters that yields good prediction abilities of nonlinear distortions induced on PCS-QAM signals. We show that reducing SOA nonlinearities is achieved by a trade-off between a high
$P_{\text{sat}}$
and a low
$\alpha_{H}$
