级联光纤混合放大器掺铒光纤放大器拉曼光纤放大器 cascading fiber hybrid amplifier EDFA RFA

摘要

基于EDFA的理论模型和受激拉曼散射效应的分析理论, 利用EDFA和RFA的增益谱互补特性, 对拉曼光纤放大器(RFA)采用两根光纤级联方式, 研究并设计了EDFA与级联光纤的RFA相结合的混合放大器结构。仿真结果表明: 在不使用增益均衡器的条件下, 所设计的混合光纤放大器在输出端得到了近似相等的输出光功率, 得到了增益平坦度为0.62 dB、波长带宽为70 nm(1 550~1 620 nm)的结果, 在密集波分复用光通信系统中有重要的应用价值。

Abstract

Based on the theoretical model of EDFA and the analysis theory of the stimulated Raman scattering effecting, making use of the complementary characteristics of the gain spectrum of EDFA and RFA, the hybrid amplifier structure combining EDFA and RFA was studied and designed with two fibers cascading RFA. The simulation results show that the hybrid fiber amplifier can obtain the approximate equal output signal power without gain equalizer. The gain flatness and the wavelength bandwidth are 0.62 dB and 70 nm (1 550~1 620 nm), respectively. It has important application value for the dense wavelength division multiplexing optical communication system.
