The model is written using Pspice8.0 soft, such that it can be directly integrated with the normal Pspice components used to simulate drive circuitry. The equivalent circuit model is based on a set of rate equations of vertical-cavity surface- emitting lasers (VCSEL's). To confirm that our model is valid, we present samples simulations that demonstrate its ability to replicate typical dc, small-signal, temperature-dependent light-current curves, transient operation, and modulation responses. Characteristics of the extracted quantum well models are discussed in detail. The predictive capability of the extracted models is demonstrated by good agreement between modeled and measured transient response pulse shapes.
