Abstract
The input/output coupling loss of vertically coupled microring resonator filters was improved by introducing busline waveguides with large spot size, i.e. the ARROW-type waveguide and the rectangular busline waveguide with a spot size transformer. Clear dropping responses were demonstrated for the ARROW based microring resonator filters and the coupling loss was successfully reduced by 22 dB.
