THE ANALYTICAL MODEL OF SRS IN SINGLE-MODE SILICA FIBER IN DENSITY WAVELENGTH DI VISION MULTIPLEXED OPTICAL COMMUNICATION SYSTEM
密集波分复用石英光纤通信系统中受激Raman散射的稳态分析模型

Assuming that the Raman gain profile of silica is a linear function, the authors have given analytic solutions of N-channel stimulated Raman scattering (SRS) st eady-state coupling wave equation. Considering the SRS cross coupling among the N-channels, the analytic solutions are applicable to systems with arbitrary chan nel separation and input light power. Theory shows, that the ratio of photon flu xes between arbitrary two channels is a base-e exponential function of the effct ive fibre length, the total input photon fluxes, and the Raman gain coefficient between the two channels. Finally, the analytic solution is compared with the nu merical one, both are in good agreement with each other.
