摘要 文章基于SOA(半导体光放大器)中的XGM(交叉增益调制)效应,提出一种实现全光UWB(超宽带)PAM(脉冲振幅调制)的方案。该方案只需要一个外部光源和一个SOA,结构简单,调制速率快。利用光通信系统软件OptiSystem对该方案进行仿真,分析了光源功率、SOA的注入电流和光源波长等系统参数对UWB PAM信号性能的影响。 On the basis of the Cross-Gain Modulation(XGM) effects in Semiconductor Optical Amplifiers(SOA),we propose a scheme for realizing all optical Ultra-Wideband(UWB) Pulse Amplitude Modulation(PAM).This scheme is simple in structure and fast in modulation as only one external optical source and one SOA are needed.We simulate the scheme using the Optisystem and analyze the impacts of the optical source power and wavelengths and the injected current to SOA and other system parameters on the PAM signal performances.
