本文用等效阶梯光纤法,求解W梯度单模光纤的等效参数(?)和(?),借用W阶梯单模光纤横场耦合特性分析的结果,对W梯度单模光纤的横场耦合进行分析。在给定的条件下,比较了W梯度单模光纤并行的横向耦合系数与W阶梯单模光纤并行的横向耦合系数,结果表明W梯度单模光纤比W阶梯单模光纤对基模光场的约束能力强,并行的横向耦合弱,其程度不是很明显的。
In this paper, we use equivalent ladder fiber method to solve the equivalent parameters (?) And (?) Of W gradient single-mode fiber. By using the results of the analysis of the transverse field coupling characteristics of W-ladder single mode fiber, Analyze. Under the given conditions, the parallel lateral coupling coefficients of W gradient single-mode fiber and W ladder single-mode fiber are compared. The results show that W gradient single-mode fiber has better performance than W ladder single-mode fiber in the fundamental mode light field Restrictive ability, lateral parallel coupling weak, its degree is not very clear.
