Abstract :
An equivalent circuit thermal model is established based on quantum cascade laser(QCL) two-level rate equation by analyzing the gain characteristic depend on the temperature in active region. The model enables the analysis of the thermal characteristics of intermediate infrared QCL using general circuit analysis software such as PSPICE. The simulation results are in agreement with reported theoretical and experimental data. That proves the practicality and accuracy of the model.
