摘　　要：详细研究了串联双环光微谐振器的光带通滤波特性 ,给出了其通带带宽的公式 ,分析了出 /入环光耦合系数和环间光耦合系数对通带特性的影响 ,计算并特别强调了滤波通带的结构特点 。The band-pass-filtering characteristics of series-coupled double-ring optical microresonators are studied. Based on the transfer function, the related bandwidth formula of the passing band is derived. The influences the into-/out-of-ring and ring-to-ring coupling coefficients on the filtering characteristics are analyzed. The structure of the passing band is calculated and emphasized. The influence of the optical loss in the microring is also analyzed.
