摘要
The present invention is a method and an apparatus for minimizing losses in wavelength selective filters. In one embodiment, an apparatus includes a waveguide bus defined in a first crystalline layer of the apparatus, for receiving incoming light, a resonator defined in the first crystalline layer, and a coupling structure defined in a second polysilicon or amorphous silicon layer of the apparatus, for coupling a selected wavelength of the incoming light from the waveguide bus to the resonator.
