Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 18:
19. A method of forming an optical device, comprising:
providing a substrate;
forming a waveguide integrated capacitor using the substrate wherein the waveguide integrated capacitor comprises a waveguide region comprising one or more photon absorption sites; and
forming a light-emitting structure over the waveguide integrated capacitor, wherein the light-emitting structure is to emit light upon application of electricity to the optical device,
wherein the waveguide region contains at least a portion of the light generated by the light-emitting structure and the one or more photon absorption sites absorbs photons of the portion of the light carried in the waveguide region and causes generation of free charge carriers relative to an intensity of the light confined in the waveguide region based on the absorbed photons resulting in a change in a conductance of the waveguide region that is proportional to the intensity of the portion of the light carried in the waveguide region.
