Abstract:
1. A semiconductor device comprising: an optical resonator for processing light at a predetermined wavelength, the optical resonator including a closed loop waveguide and a central region surrounded by the closed loop waveguide; and a waveguide structure spaced from the closed loop waveguide of the optical resonator to provide for evanescent-wave optical coupling therebetween; wherein both the optical resonator and the waveguide structure are formed in an epitaxial layer structure deposited on a substrate, the epitaxial layer structure including at least one modulation doped quantum well interface; and wherein the central region of the optical resonator includes a first electrode with at least one ion implant region formed under the first electrode and extending through the at least one modulation doped quantum well interface of the epitaxial layer structure adjacent the closed loop waveguide, wherein the at least one ion implant region provides for lateral confinement of light within the closed loop waveguide and for funneling of current from the first electrode away from the central region and through the closed loop waveguide of the optical resonator.
