Patent ID: 8368995

Claim:
An opto-electronic integrated circuit comprising: a substrate comprising a silicon material; a set of optical transmitters, each comprising: a gain medium coupled to the substrate, wherein the gain medium includes a compound semiconductor material; an optical modulator optically coupled to the gain medium; a waveguide disposed in the substrate and optically coupled to the gain medium; a first wavelength selective element characterized by a first reflectance spectrum and disposed in the substrate; a second wavelength selective element characterized by a second reflectance spectrum and disposed in the substrate; an optical coupler disposed in the substrate and joining the first wavelength selective element, the second wavelength selective element, and the waveguide; and an output mirror; a set of optical receivers, each comprising: a waveguide disposed in the silicon material; an optical detector bonded to the silicon material; and a bonding region disposed between the silicon material and the optical detector, wherein the bonding region comprises: a metal-assisted bond at a first portion of the bonding region, wherein the metal-assisted bond includes an interface layer positioned between the silicon material and the optical detector; and a direct semiconductor-semiconductor bond at a second portion of the bonding region; and control electronics disposed in the substrate and electrically coupled to the set of optical transmitters and the set of optical receivers.
