基于单模光纤的非对称熔锥型零耦合器结构的理论模型与实验研究

THEORETICAL MODEL OF ASYMMETRIC FUSED TAPER SINGLE-MODE FIBER NULL COUPLER AND EXPERIMENT

我们报道了一种新型非对称熔锥型零耦合器结构的理论模型 ,采用椭圆近似的方法得到了零耦合器渐变区和束腰区的横截面的变化函数 。

Authors report on a theoretical model of Asymmetric Fused Tapar Fiber Null Coupler.It is used ellipse to approximate cross section of null coupler,acquire function of the taper transition and waist.The experiment results meet the theoretical model.
