Özet

A model is developed for the carrier induced refractive-index change in Quantum-well (QW) lasers which affects different mechanisms. The model is based on Artificial Neural Network (ANN) which provides a powerful approach for setting up a complex non-linear model. Different algorithms are tried and tested for different injection current levels. Both the training and the test results for refractive-index change are in very good agreement with the experimental findings reported elsewhere.
