摘要

本文应用耦合模理论

研究下述情况下

由单模阶梯光纤随机微弯所引起的非本征损耗:（1）不考虑纤芯对LP

场形的影响;（2）考虑上述影响。假设光纤随机微弯的自相关函数是高斯函数

本方法可推广用来研究光纤在其它几何畸变或折射率畸变时所引起的非本征损耗。

Abstract

In this paper

the nonintrinsic loss caused by random microbend for single-mode step-index fibers is researched using the coupled mode theory under the following conditions: （1） Not considering the effect of fiber core on shape of field of cladding mode LP1j （2） considering the above-mentioned effect. We assume that the autocorrelation function of random microbend of fibers is Gaussian.This method canbe extended to study the nonintrinsic loss caused by other geometry or refractive-index deforming fibers.
