摘要：
In this paper, the large signal circuit model of a QW laser diode has been derived from rate equations and implemented using the circuit simulation program PSPICE. This model, in conjunction with the optical fibre and photodetector model constituting an optical link, has been simulated by generating eye diagrams for different pulse formats. Further, a small signal equivalent circuit of the QW laser diode based on the small signal analysis of rate equations is presented and the frequency effects on the modulation properties of quantum well lasers are studied by simulating the model. Gain switching in QW lasers has also been studied using this technique.
