单模光纤参数对布里渊散射阈值的影响

摘要

Both Spontaneous Brillouin scattering model and stimulated Brillouin scattering model are applied for the analysis of the threshold for stimulated Bdllouin scattering in short and long SMF respectively at 1550nm communication window.For short distance transmission the dependency of the threshold exponential gain on fiber numerical aperture and fiber length is studied.%应用自发布里渊散射模型和受激布里渊散射模型,在1550nm通信窗口,分别对短距离和长距离普通单模光纤中的布里渊散射阈值进行了研究.对于短距离传输,分析了自发布里渊阈值增益系数与光纤数值孔径以及有效长度的依赖关系.
