Abstract:
1. A source comprising: a thermally conductive substrate; a quantum well gain medium that is directly bonded to the thermally conductive substrate, the gain medium having a base side and an epi side, the gain medium further comprising a quantum well stack, waveguide layers, and a bond layer; wherein the quantum well stack is comprised of a plurality of semiconductor layers forming quantum wells and barrier regions; wherein the waveguide layers are disposed on the epi side and the base side of the quantum well stack and are optically and electrically conductive; and wherein the bond layer is a metallic or electrically conductive layer disposed on one of the waveguide layers to form a bond between the gain medium and the thermally conductive substrate; and an optical resonator having at least one optical feedback element spatially removed from the gain medium.
