摘要
针对密集波分复用光纤通信系统中喇曼光纤放大器的增益平坦度较低、带宽较窄的问题,从前向多泵浦喇曼放大器耦合方程入手,采用龙格-库塔法,使用碲基光纤作为多泵浦喇曼放大器的增益光纤,通过Matlab分析了多波长泵浦中泵浦数量、泵浦功率和光纤长度对增益及增益平坦度的影响,最终通过采用6个泵浦,并合理设置泵浦功率,实现了100 nm传输带宽的仿真。
In the dense wavelength division multiplexing optical fiber communication system,the gain flatness of the Raman fiber amplifier is low and the bandwidth is narrow.Starting with the coupling equation of the front-end multi-pumped Raman amplifier,using the Runge Kutta method and the tellurium based fiber as the gain fiber of the multi-pumped Raman amplifier,the number of pumps,pump power and light in the multi wavelength pumping are analyzed by Matlab.Finally,the simulation of 100 nm transmission bandwidth is realized by using six pumps and setting pump power reasonably.
