摘　　要：将通信光纤的末端拉制成锥形 ,利用光信号在光纤锥形区特有的传输和耦合特性 ,实现了光纤的耦合、连接和分束 用耦合模理论分析了锥形光纤间的传输和耦合性质 。Through melting and pulling the end of a fiber into a tapered area, optical fiber transmission and fiber coupling, as well as fiber beam splitting can be realized for the special transmission and coupling characteristic in the tapered area. Optical fiber transmission and fiber coupling between two tapered fibers are analyzed. Also the coupling efficiencies of two tapered fibers versus the vertical distance and the overlap length of two tapered regions of them are analyzed.
