有源光纤环形腔滤波器优化

Optimization of Active Optical Fiber Ring Resonator Filter

本文引入输入光线宽因子，利用多光束干涉理论，给出了有源光纤环形腔滤波器输出光谱密度等公式．利用这些公式可以对腔的结构和参数方便地进行理论分析和优化设计．当使该有源滤波器工作在锁定状态时，可得到窄线宽光输出．

In this paper, the linewidth factor of input light is introduced, and the spectrum density of active optical fiber ring resonator filter and other correlated formulas are also proposed by using multiple light interference theory. Based on these formulas, it is convenient to optimize the structure and parameters of active optical fiber ring resonator. When this active filter is working in lock-in state, the stabilized and narrowed output light is produced.
