| Abstract: | 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. |
