拉曼增益系数可分离光纤中的受激拉曼散射

给出了拉曼增益系数分离光纤的定义，在考虑了N个单色光之间的两两受激拉曼散射，得到了这种光纤中单向传输的N个不同的单色光之间的受激拉曼散射（SRS）稳态耦合波方程的解析解。它适用于各单色光功率任意大小、光频率分布不均匀时的一般情况。这一结果可应用于光纤通信系统、拉曼光纤放大器和拉曼光纤激光器的设计与分析。最后把解析解与数值解进行了比较，两者取得了很好的一致。

Stimulated Raman Scattering in Raman Gain Separated Fiber

The Raman gain separated fiber is designated. The analytic solutions of N-channels stimulated Raman scattering (SRS) steady-state coupling wave equation in the fibers is given. As considering the SRS cross coupling among the N-channels, the analytic solutions are applicable to arbitrary channel separation and input photon fluxes. These results can be used to analyze and design the optical fiber communication systems, Raman fiber amplifier and lasers. Finally, the analytic solution is compared with numerical one, both are in very good agreement.
