57 Abstract AB [EN] A semiconductor device that includes an optical resonator spaced from a waveguide structure to provide for evanescent-wave optical coupling therebetween. The optical resonator includes a closed loop waveguide defined by an epitaxial layer structure that includes at least one quantum well. The semiconductor device also includes circuitry configured to supply an electrical signal that flows within the epitaxial layer structure of the closed loop waveguide. The electrical signal affects charge density in at least quantum well of the closed loop waveguide and controls refractive index of the closed loop waveguide. In one embodiment, the electrical signal is a DC current signal that flows within a vertical thyristor structure of the closed loop waveguide to control refractive index of the closed loop waveguide such that resonance frequency of the closed loop waveguide corresponds to a characteristic wavelength of light.
