摘要
半导体激光器是光通信中的核心器件之一,广泛应用于城域间的骨干网。光电集成电路计算机辅助设计是对光电器件建模仿真的重要方法,在光通信中起着举足轻重的作用。推导了激光器小信号频率响应的计算公式,研究了激光器的封装寄生参量的谐振现象,利用这种谐振效应对激光器的频率响应特性进行有效补偿,采用数据用电路仿真软件PSpice对建立的等效电路模型进行小信号频率响应分析得出3dB频率响应带宽。
Laser diode is one of the core devices in optical communications,and is widely used in communication backbone network between metropolitans.Optoelectronic integrated circuit computer-aided design is an important method for optoelectronic device modeling,and plays an important role in optical communication.The small signal frequency response formula of laser diode is deduced,and the resonance phenomenon of package parasitic parameters is studied,and such a resonance effect is used on the compensation of the chip′s frequency response characteristics.Finally circuit simulation software PSpice is used to analyze the circuit model for small signal frequency response,and the frequency response bandwidth of 3 dB is obtained.
