A NOVEL DYNAMIC ANALYSIS AND SIMULATION FOR QUANTUM-WELL DISTRIBUTED FEEDBACK LASER (QW-DFB)

A method for using the popular math package MATLAB and simulink to simulate the behavior of distributed feedback quantum- well semiconductor laser diodes using the rate equation that describe them is presented. A large-signal model for threshold determination and operating point selection is discussed. Small-signal properties of interest can be investigated using a state-space description of a linearized version of the rate equations, based on their Jacobian.
