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 present disclosure provides for laser integration into photonic platforms in which a first wafer, including a first substrate and a first insulator that includes a first plurality of dies that each include a first set of optical waveguides, is bonded to a second wafer, including a second substrate and a second insulator that includes a second plurality of dies that each include a second set of optical waveguides. The bond between the two wafers defines a wafer bond interface joining the first insulator with the second insulator and vertically aligning the first plurality of dies with the second plurality of dies such that respective first sets of optical waveguides are optically coupled with respective second sets of optical waveguides.
