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.

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.

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.
