Abstract
A multichannel optical waveguide resonator having a plurality of evanescently coupled optical dielectric waveguide rings and an input optical waveguide and an output optical waveguide located adjacent to one of the waveguide rings. The input and output dielectric waveguides are located for evanescent wave coupling of light into and out of one of the waveguide rings. The perimeters of the waveguide rings and the spacing therebetween are selected for evanescent coupling between the waveguides and so that light in the input waveguide reinforces with light in one of the concentric waveguides to create a resonator having an increased effective perimeter.
