摘要

文章对光纤拉曼放大器系统应用于NZ-DSF（非零色散位移光纤）中存在的泵浦与噪声之间的FWM（四波混频）现象进行了理论分析和实验证明。在理论分析中推断出第4束光出现的位置

并且在实验中加以证明。由此基础上提出

在光纤拉曼放大器系统中应用NZ-DSF时

泵浦波长应当远离零色散位移点

避免FWM效应的产生。

Abstract

This paper analyzes the Four Wave Mixing（FWM） phenomenon between pump and noise in the application of Fiber Raman Amplifiers（FRA） in Non-Zero Dispersion Shifted Fibers（NZ-DSF） and deduces the position where the fourth beam of light appears and proves it in experiments.On this basis

it suggests that when FRA are applied in NZ-DSF

the pump wavelength should be far away from the zero dispersion shift point

so as to avoid the production of FWM effects.
