An implementation of an improved circuit model of semiconductor lasers which can model the reflection coefficient more accurately is presented and the comparison between the improved model and the conventional counterpart is made. The SDD(Symbolic Defined Devices)component in ADS(Advanced Design Systems)is used and the transformation of the rate equations is taken to improve the convergence of the model. The reflection coefficient of the lasers is simulated with the model under different bias conditions and is compared with the experimental results. The accuracy of the improved model is first time verified in large signal simulation.
