Abstract
The present invention provides a micro-resonator including a plurality of waveguides forming optic junctions therebetween, with adjacent waveguides having different core permittivities and different cladding permittivities. Adjacent waveguides are mode-matched through adjustments of the core permittivities and the cladding permittivities of the waveguides to reduce or eliminate junction radiation, thereby providing high performance.
