Abstract: An optical apparatus comprises a semiconductor substrate, and a supermode filtering waveguide (SFW) emitter disposed on the semiconductor substrate. The SFW emitter comprises a first optical waveguide, a spacer layer, and a second optical waveguide spaced apart from the first optical waveguide by the spacer layer. The second optical waveguide is evanescently coupled with the first optical waveguide and is configured, in conjunction with the first waveguide, to selectively propagate only a first mode of a plurality of optical modes. The SFW emitter further comprises an optically active region disposed in one of the first optical waveguide and the second optical waveguide.

Abstract: Embodiments provide for a photonic platform, comprising: a silicon component; a III-V component; and a bonding layer contacting the silicon component on one side and the III-V component on the opposite side; wherein the silicon component comprises: a silicon substrate; a dielectric, contacting the silicon substrate on one face and the bonding layer on the opposite face; a silicon cores disposed in the dielectric; and wherein the III-V component comprises: a III-V cladding; a III-V contact, having a first side that contacts the bonding layer; and an active region, disposed on the III-V contact and separating the III-V contact from the III-V cladding, wherein the active region is located relative to the silicon cores to define an optical path that includes the active region and the silicon cores.

Abstract: The structures and methods described include an inverted slab-coupled optical waveguide (SCOW) structure, which inverts the polarity of a typical SCOW diode and includes an active region located at an inverted side of the slab section of the inverted SCOW. The inverted SCOWs provide for easily adjustable optical mode confinement or overlap in an active region/gain medium without the risks of generating multiple spatial modes or high electrical resistance associated with traditional non-inverted SCOWs.
