摘要
利用光线光学的原理，提出了求解双芯自聚焦透镜耦合损耗的数学模型，利用该模型得出了自聚焦透镜耦合损耗与双芯间距的关系曲线。实际制作的双芯自聚焦透镜耦合系统，两路光纤到光纤的耦合损耗分别为０．７９ｄＢ和０．８５ｄＢ。
In this paper, on tile basis of theory of ray optics, a mathematical model used to compute the coupling loss of GRIN lens with twin-core fiber has been described. According to this model, we show that the relative curve between coupling loss of GRIN lens and distance of twin-core fiber is obtained. In our pratical coupling system of GRIN lens with twin-core fiber, coupling loss of twin core is 0. 79 dB、0. 85 dB, respectively.
