Abstract

Analysis of asymmetric multi quantum well (AMQW) laser is presented using an equivalent circuit model based on carrier and photon rate equations. The circuit model has been implemented on SPICE circuit simulator. Also, the numerical solution of the rate equations is made by finite difference time domain (FDTD) method in order to compare the results obtained from two approaches. It is shown that the transient response characteristics, including the frequency and damping factor of the relaxation oscillations, the resonant peak, and the turn on delay, which are resulted from the circuit modeling, are in good agreement with the numerical simulation results.
