Analysis of Coupling Power for Fused-Biconical 2×6 Single-Mode Optical Fiber Coupler
摘要
以线性耦合模方程为基础,推导了在弱熔、弱耦条件下2×6熔融拉锥型单模光纤耦合器的传播常量、本征模以及各端口的功率分布情况,并利用“熔融拉锥”法研制成功了两层排列结构的2×6单模光纤耦合器,实验得到的功率分布与理论分析结果基本一致。
Abstract
Based on linear couple mode equation, propagation constants, eigenmodes and power coupling characteristics of 2×6 fused-biconical single-mode fiber coupler with weak fusion and weak couple were derived. The two layers 2×6 fiber coupler was fabricated by fused-biconical method. Experimental results obtained about spectral responses of the coupler are in good agreement with the theoretical results.
