Simulation of strained QW lasers

A large circuit model of a strained quantum well laser has been developed from rate equations. The electrical and optical properties of the laser are dealt with, and interactions between these quantities are taken into account The model is compatible with a more versatile, universally applicable and readily available circuit simulation package PSPICE, and has added advantage that each of the elements in the model has a physical interpretation. This enables the dynamic operation of the laser to be easily visualized. The application of the model are illustrated with a number of simulated laser response characteristics.
