Abstract
In one example, a chip-scale emitter includes a resonator formed in a waveguide, wherein the resonator includes a first grating formed in the waveguide and a second grating formed in the waveguide that is separate from the first grating; and a scattering element consisting of a single defect in the waveguide, wherein the scattering element is positioned between the first grating and the second grating in the waveguide.
