Abstract

A different method and single model to determine the linewidth enhancement factor (a (Alpha) parameter) for narrow and wide GaAs Quantum-wells (QWs) as a function of modal peak gain and current density is presented. Based on the Artificial Neural Network (ANN) modeling approach, different learning algorithms are trained and tested. Both the training and the test results are in very good agreement with the experimental results reported elsewhere.
