摘要
提出了用同向泵浦的剩余泵浦功率作为反向泵浦的泵浦功率迭代初值 ,用Lorentz线型拟合喇曼增益系数 ,采用简明的数学模型 ,对比分析了同向。
With a simplified model for calculating optical gain of Raman amplifier under Lorentz Raman profile approximation and predicting the pump power at the fiber start point for counter pump with the residual pump power for co pump, gain characteristics of co pump and counter pump fiber Raman amplifier are compared and analyzed. The effect of signal to signal interaction on gain spectrum is also analyzed.
