半导体激光器电路模型在ADS中的实现

Semiconductor laser circuit model implementation in the ADS

在软件ADS(Advanced designed systems)中利用SDD(Symbolically defined device)器件实现了半导体激光器的电路模型。在建模过程中对速率方程进行变换以改善由于数值溢出与数值解不唯一引起的收敛性问题,使得仿真结果可以收敛于真实的物理解。利用此模型在ADS中对于半导体激光器的直流特性、交流特性与瞬态特性进行了仿真。

A circuit model for semiconductor lasers is realized in ADS （ Advanced designed systems ） using SDD （ Symbolically defined device ） components. The transformation of the rate equations is taken to improve the convergence performance which is af-fected by the numerical overflow and multiple solutions of the rate equations. The DC, AC, and transient characteristics of the semi-conductor lasers are simulated with the model.
