摘要

文章提出了两种利用SOA（半导体光放大器）的XGM（交叉增益调制）和FBG（光纤布拉格光栅）光学生成对称型UWB（超宽带）信号的新方法。分析了该方法的工作原理并进行了仿真实验

分别得到了符合FCC（美国联邦通信委员会）标准的中心频率为5.35 GHz、相对带宽为114%以及中心频率为4.7 GHz、相对带宽为132%的对称型UWB信号

仿真结果验证了该方法的可行性。文章还分析了这两种方法存在的问题。

Abstract

This paper proposes two new methods for the generation of UWB doublet signals using the Cross-Gain Modulation（XGM） effect of Semiconductor Optical Amplifiers（SOA） and the Fiber Bragg Grating（FBG） optics.It analyzes their working principles and performs simulation experiments on two systems

obtaining UWB doublet signals that conform to the FCC standard

one with a center frequency of 5.35 GHz and a relative bandwidth of 114% and the other with a center frequency of 4.7 GHz and a relative bandwidth of 132% respectively.The simulation results verify the feasibility of the proposed methods.Finally

it analyzes the existing problems of these two methods.
