초록
This paper has analyzed the static and dynamic characteristics of a single ring-resonator-based optical WDM add/drop filter. The analysis has shown that the coupling coefficient of the coupler between a feeding waveguide and ring waveguide greatly influences the dynamic characteristics of a ring filter. Another determining factor was one round trip time of beam in a ring waveguide. Also, coupling coefficient has had influence on static on-chip losses in both thru and add/drop operation in a ring-resonator filter array. Considering both static and dynamic characteristics, a suitable range of coupling coefficients exists. Also, sideband rejection ratio of single ring resonator based WDM filter was investigated. Our method can provide a guide for the design and realization of a single ring-resonator based WDM add/drop filter. © Springer Science+Business Media, LLC. 2012.
