Integrated optical filters utilizing resonators |
摘要 |
A filtering method and optical filter structure are presented. The structure comprises an input waveguide, an output waveguide, and a filter stage formed by at least one closed loop resonator optically coupled to the input and output waveguides. A level of the coupling from each of the waveguides to the resonator is at least 5 times greater than a loss-per-revolution of the resonator. The filter structure thus provides for reducing a bandwidth and insertion loss while filtering at least one optical channel from a multi-channel light signal.
