摘要

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6GHz、相对带宽为143%的二阶信号和中心频率为8GHz、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。

Abstract

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 9.0and obtains 2-order UWB signals with the central frequency of 6GHz and relative bandwidth of 143% and 3-order UWB signals with the central frequency of8 GHz and relative bandwidth of 120%

both in compliance with the FCC requirements on UWB signals.Furthermore

it analyzes the impacts of the input pulse signal width

detecting light and pump optical power on the generated signals.
