Abstract: Based on the dynamic analysis and numerical computation of quantum cascade laser(QCL), a simple equivalent circuit model of QCL was established, in which we considered the spontaneous emission effect for QCL's start delay. The direct current(DC), transient and frequency response characteristics of QCL were obtained by means of the circuit simulation of PSPICE program, and some relevant parameters that may affect the QCL performance have been analyzed. The results of simulation are consistent with that of numerical calculation in previous literatures.
