摘要
提出利用级联光纤环镜构成全光纤G -T干涉仪,并运用光波叠加原理和传输矩阵理论详细研究了其滤波和相位特性,给出了其相移表达式,分析了级联光纤环镜中各参数对其相位特性的影响。在此基础上,设计了一种基于级联光纤环镜G -T腔的新型全光纤交错复用器,该器件光学结构简单,具有DWDM系统所需的截止度和平坦度。
We present an all-fiber G-T resonator formed by cascading two fiber loop mirrors.Based on the superposition theory and the transfer function,the wave filtering and nonlinear phase feature of which is studied and the ralated phase shift formula of the reflective beam is derived.The influences of its parameter on the phase characteristics are analyzed.An novel interleaver based on the all-fiber G-T resonator is designed.The theoretic model is simulated and calculated to meet the need of the flatness and the sharpness in the 50GHz DWDM systems.
