用BPM对单模光纤连接损耗的研究

Using the BPM research on single mode optical fiber connection loss

对于单模光纤的连接损耗的计算,通常所用的模场解析法,需要将光纤的模场用高斯场近似才能得到,各种影响因素共同存在时连接损耗的计算比较困难。本文利用BPM方法对光纤连接处的光场进行模拟数值计算,进而得到光纤连接的传输效率。

mode field analytical method is used to calculate single-mode optical fiber connection loss. this method always use gaussian mode to approximately calculate the connection loss and it is hard to get the connection loss with varied influencing factors, this article use the BPM to calculate the optical field on the joint of two same fibers and get the transmission efficiency.
