| 摘 要： | 介绍了动态增益控制的必要性，对动态拉曼传输方程进行了简化，并将其以矩阵形式表示，从而减少了方程的数量，提高了计算速度。由拉曼传输耦合方程推出一种适用于分布式拉曼放大器实时控制的自动控制算法。考虑工程需要，该算法忽略了噪声功率、泵浦间的受激拉曼效应，以及信号和泵浦间受激拉曼效应对泵浦功率的损耗。结果表明该算法能够达到快速抑制输入信号功率突变引起的输出功率／增益波动的目的。

| Abstract: | The essentiality of dynamic gain control is introduced.The Raman propagation equations are simplified and written with the format of matrix.It can increase the speed of calculating the equations with this format because of the decrease of equations.Lastly,the real-time auto-control algorithm for DRA is gotten from Raman coupling equations.During solving the propagation equations,the noise power,stimulated Raman scattering(SRS)of pump-pump and the pump power attenuation caused by SRS of signal-pump are ignor... |
