摘要
为了增加喇曼光纤放大器(RFA)的输出带宽,减小增益平坦度。利用Opti System软件仿真分析了不同参数设置下的增益特性与泵浦源的关系,对泵浦功率、泵浦波长、光纤长度和有效作用面积进行了优化设计与仿真。仿真结果表明:提出的优化方法可使RFA的增益在设定范围内获得最大值,并且通过改变相关参数得到较好的增益平坦度。
In order to increase the output bandwidth of Raman fiber amplifier(RFA) and reduce the gain flatness. The relationship between the gain characteristics and the pump source under different parameter settings is analyzed by using OptiSystem software. The pump power, pump wavelength, fiber length and effective area are optimized and simulated. The simulation results show that the proposed optimization method can maximize the gain of RFA within the set range, and obtain better gain flatness by changing the relevant parameters.
