提出了一种利用 SOA(半导体光放大器)的增益饱和效应及 XGM(交叉增益调制)效应同时产生二阶及三阶 UWB(超宽带)信号的方案，分析了其工作原理，并采用光子模拟软件进行了仿真实验，得到了中心频率为6 GHz、相对带宽为143%的二阶信号和中心频率为8 GHz、相对带宽为120%的三阶信号，两者均符合FCC(美国联邦通信委员会)对UWB信号的规定。同时，还分析了输入脉冲信号宽度、探测光及泵浦光功率对生成的 UWB信号的影响。

This paper presents a scheme for the simultaneous generation of 2-and 3-order Ultra-Wide Band (UWB)signals on the basis of the Self-Gain Saturation (SGS)and Cross-Gain Modulation (XGM)effects of Semiconductor Optical Amplifiers (SOA)and analyzes its operating principle.It simulates this scheme by using Optisystem 9.0 and obtains 2-order UWB signals with the central frequency of 6 GHz and relative bandwidth of 143% and 3-order UWB signals with the central frequency of 8 GHz and relative bandwidth of 120%,both in compliance with the FCC requirements on UWB signals.Furthermore,it ana-lyzes the impacts of the input pulse signal width,detecting light and pump optical power on the generated signals.
