RADIATION-FREE OPTICAL CAVITY

摘要

The present invention provides a micro-resonator including a plurality of waveguides forming optic junctions therebetween, each waveguide being formed of waveguide sections with adjacent waveguide sections having different core permittivities and different cladding permittivities and at least one waveguide section comprising a defect layer. Adjacent waveguide sections 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.
