基于双平行相位调制器的微波光子链路系统
Microwave photonic links based on dual-parallel phase modulators
摘要
Abstract
As the output signal of the phase modulator can not be directly detected by PD,the dual-parallel phase modulators have been used to build microwave photonic links that can achieve direct detection.The dual-parallel phase modulators mi-crowave photonic links use two phase modulators.By setting the phase deviation difference between two PM asπ,two phase modulated signals do not cancelleach other at the receiving.Then the phase modulated signals can transmit in direct detec-tion.This paper analyzes the theory of the links and simulates the model of the links.The results of the simulation show this link can effectively transmit phase modulated signal to the receiver and has some features such as simple structure,low noise,etc.关键词
