  • 摘要

    从耦合模方程出发，分析了全光纤非对称熔融拉锥型耦合器的带宽特性，提出和论证了全波(O+E+S+C+L band)耦合器的制作方案，并且在工艺上实现了全波耦合，其带宽达到了390nm(1260—1650)，分束比1∶99；附加损耗01dB.

     

    Abstract

    This paper, on the basis of coupled-mode equations, analyzes the bandwidth characteristic of asymmetric fused biconical taper (FBT) coupler, and proposes and proves a solution of all-wave coupler (O+E+S+C+L band).We also succeed in making all-wave couplers with a bandwidth of 390nm, while the excess loss is only 0.1 dB and the coupling ratio is 1∶99
