摘要 从石英光纤具有的近似线性喇曼增益的特点出发,给出了等信道间隔、等初始输入光子通量条件下前向N信道受激喇曼散射(SRS)稳态光子转换方程的解析解.这个解析解是在考虑了N个信号光之间串话下得到的,它适用于任意大小的信号光.同时指出,在传输过程中,SRS的作用使相邻信道的信号光光子通量保持等比性.公比值随光纤的有效作用距离、总的初始输入光子通量和对应于信道间隔的喇曼增益系数而变化.而总信号光光子通量可表示为N项等比级数.解析解与数值解进行了比较。 Assuming that the Raman gain profile of silica is a linear function, the author has given analytic solutions of N \|channel stimulated Raman scattering (SRS) steady\|state coupling wave equation with equal (but arbitrary) channel separation and input photon fluxed. Considering the SRS cross coupling among the N \|channels, the analytic solutions are applicable to arbitrary amount of signals in the N \|channels. It also has been pointed out that the ratio of photon fluxes between neighboring channels is equal. The common ratio varies with the effective length and the total input photon fluxes and the Raman gain coefficient of the channel separation. The total output photon flux is geometric series. Finally, the analytic solution is compared with numerical one, both are in very good agreement with each other.
