    Abstract: An adiabatic elliptical optical coupler device is provided comprising: a substrate having an edge; a first waveguide on the substrate, the first waveguide comprising a constant-width region and a tapered region terminating at the edge of the substrate, the tapered region having a smaller width at the edge than at the constant-width region; and, a pair of second waveguides on the substrate, and located on either side of the tapered region, each of the pair of the second waveguides terminating at the edge at a first end and extending to a second end adjacent the constant-width region, and distal the first end; at least a portion of each of the pair of second waveguides being tapered, and optically coupled to the first waveguide to transition a mode of an optical signal in the first waveguide from an elliptical mode at the edge towards a confined mode.

    IPC: G02B6/12

    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.

    IPC: G02B6/30

    Abstract: An example device comprises: a substrate comprising a waveguide material having a waveguide refractive index (RIWG); a first layer of oxide on the substrate having an RI1 lower than the RIWG; a waveguide on the first oxide layer, the waveguide comprising the waveguide material having the RIWG; a second oxide layer on the waveguide and the first oxide layer, the second oxide layer having a second RI2 higher than the RI1 and less than the RIWG, the first oxide layer, the waveguide and the second oxide layer forming an end face for light coupling, and the waveguide extending inwards from the end face and increasing in effective RI from the end face; and an index matching material on the second oxide layer that encapsulates at least the second oxide layer and the end face, a respective RI of the index matching material being about index matched to the RI1.

    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.
