掺铒光纤中的后向瑞利散射的研究

Study of Rayleigh Backscattering in Erbium-Doped Fibers

本文对掺铒光纤的瑞利散射进行了理论分析，计算了后向瑞利散射光与泵浦功率、掺铒光纤长度、信号光功率的关系，并提出了用隔离器减小后向瑞利散射光的方法。

This paper theoretically analyzes the Rayleigh backscattering of erbium-doped fiber, calculates the relation between the Rayleigh backscattering light and pump power,erbium-doped fiber length, and signal power, and offers a mean of using an isolator to reduce the Rayleigh backscattering light.
