本文利用通用电路分析软件SPICE中的受控元件和器件模型建立了一个新的半导体激光器电路模型。这个模型,可以用来模拟激光器的非线性、瞬态响应、小信号频率响应、阻抗特性以及发射光功率与注入电流的关系等,它使得激光器和它的相关电子电路能够统一地用SPICE分析。计算机的模拟结果与已报道的理论和实验值相一致。 In this paper, a new semiconductor laser circuit model is established by using controlled components and device models in general circuit analysis software SPICE. This model can be used to simulate the laser nonlinearity, transient response, small signal frequency response, impedance characteristics and the relationship between the emission power and injection current, which enables the laser and its associated electronic circuits to be uniformly analyzed by SPICE. Computer simulation results have been consistent with the reported theoretical and experimental values.
