Abstract: A carrier laser device assembly is provided in which a visible region of a laser that includes an output portion and/or output portion of a waveguide of the laser is visible to an imaging system when the laser is attached to a carrier. The laser may be burned-in and/or tested prior to attachment to a photonic integrated circuit. The output portion and/or output portion of waveguide may be aligned with a corresponding input portion and/or input portion of a waveguide of the PIC as the laser assembly is being attached to the PIC via imaging of the visible portion by the imaging system.

Abstract: A device that includes an optical coupler with a waveguide and waveguide index matched materials at an edge of a substrate, and a method of forming the device, is provided herein. The device comprises: a substrate having an edge, and an opening formed therein adjacent the edge; a layer of insulator on the substrate, which forms a bridge across the opening at the edge; a waveguide on the layer of insulator, the waveguide comprising a constant-width region and a tapered region terminating at the edge in a region of the opening; a first layer of optical epoxy in the opening, the optical epoxy indexed matched to the layer of insulator; and, a second layer of the optical epoxy on the tapered region, such that the optical epoxy optically contains an optical signal leaking from the waveguide in the tapered region.

Abstract: An optical ring resonator structure with a backside recess is provided at a device. The device includes: a substrate having a device-side and a backside opposite the device-side; an optical ring resonator located on the device-side of the substrate; a heater having a shape complementary to the optical ring resonator, the heater positioned to heat the optical ring resonator; and one or more metal traces that connect at least to the heater, the metal traces configured to provide power to the heater and extending outward from the heater. The device further includes a recess on the backside of the substrate, the recess centered on the optical ring resonator, and having a diameter larger than both respective outer diameters of the optical ring resonator and the heater, the recess further extending laterally into a region of the one or more metal traces.
