Abstract
A fully confined dual frequency optical resonator configured for optical coupling to light having a first frequency ω. The dual frequency optical resonator includes a plurality of alternating layer pairs configured in a grating configuration, each layer pair having a first layer formed of a first material and a second layer formed of a second material, the first material and second material being different materials. Each layer having a thickness different than a thickness of an adjacent layer to provide thereby aperiodic layer pairs, the thicknesses of adjacent layers being selected to create, via wave interference with each layer, optical resonances at the first frequency ωand a second frequency ωwhich is a harmonic of ω, and to ensure a maximum spatial overlap between confined modes over the materials such that an overall quality factor Q of at least 1000 is achieved.
