一种新型结构的单模光纤1×4分束器

A New Structure of 1×4 Single-Mode Optical Fiber Splitters

以线性耦合波方程为基础，分析了具有平面型结构的五光纤耦合系统的功率耦合特性，提出了研制新型结构的单模光纤１×４分束器的方法，并经实验验证。所研制的１×４分束器的性能和外形尺寸与常规的２×２单模光纤耦合器相比，都较为接近。

Based on the linearly coupled mode equations, we have analyzed couPledpoWer characteristics of the coupling system consisting of five optical fibers. A mothed tofabri￣ new Structure of 1 × 4 splitters is proPOsed and experimentally demonstrated.The characteristics and dimentions of the obtained 1 × 4 splitter are almost the same ascommon 2 × 2 coupler.
