Our goal in this paper is to evaluate the performance of quantum cascaded lasers (QCL's). The tools that we are used are the VisSim technique along with the block diagram programming procedures. The benefits of using this modeling language are the simplicity of carrying out the performance's measurement through computer simulation instead of setting up a practical procedure which becomes expensive as well as the difficulty of its management. The implemented models can help designers and scientists to optimize their devices to meet their requirements.
