光纤拉曼放大器的最大拉曼增益特性

为了分析同向抽运与反向抽运光纤拉曼放大器的最大拉曼增益，基于耦合微分方程，采用理论推导的方法，根据不同抽运结构下信号光放大的不同实际情况定义并推导出同向抽运光纤拉曼放大器和反向抽运光纤拉曼放大器的最大拉曼增益公式。然后，详细分析了各个参数对两种抽运方式下光纤拉曼放大器的最大拉曼增益的影响。对两种抽运方式下相同参数引起的最大拉曼增益进行了比较。结果表明，同样的参数对同向抽运与反向抽运光纤拉曼放大器最大拉曼增益的影响有相同的地方，也有不同的地方。最后，将最大拉曼增益和常用的开关增益进行了比较。对光纤拉曼放大器的实验、成本估计和器件效率等研究有重要参考意义。

Abstract

In order to analyze the maximum Raman gain of forward-pumped and backward-pumped fibre Raman amplifier(FRA), by theoretical derivation method for solving the differential coupling equations, the formulas for the maximum Raman gain of forward-pumped and backward-pumped FRA were defined and obtained based on different signal amplification process with different pumping structure. Using these new formulas, the effects of input signal power, input pump power, Raman gain coefficient per area, fibre attenuation and the pump to signal frequency ratio on the maximum Raman gain of forward-pumped and backward-pumped FRA were investigated in detail in the condition that the parameters were all of their typical values. Some results are consistent with results of involved references. Besides, maximum Raman gains of two pumping ways under the same parameter were compared. Finally, maximum Raman gain and on-off gain which was frequently-used were compared. These results are creative and helpful to the experiment study of FRA.
