从三层速率方程推导出多量子阱激光器的等效电路模型，并用数量而不是密度来描述载流子及光子行为，避开了传统方法中处处都要涉及到的体积参量，解释了传统的二层模型所不能解释的多量子阱(MQW)激光器中多量子阱内载流子不均匀分布问题，用SPICE进行了调制特性的模拟及讨论。激光器件的模拟以层次性的方式实现，对使用EDA工具进行集成光学器件和系统仿真进行了探索。

A study of equivalent circuit model of MQW lasers derived from three-level rate equations is carried out. It can explain the carrier distribution, which can not be explained by traditional two-level model. The simulation of modulation behavior is implemented in SPICE. Results of various modulation properties from the simulator are discussed. Especially, the scheme was implemented in a hierarchic way, which provides a much easier management and a help to realize photonic design automation (PDA).
