Abstract: A line-shaped heater and an optical resonator with portions on opposite sides of the line-shaped heater are provided. In particular a device provided herein includes: one or more inputs; one or more outputs; one or more optical waveguides configured to: receive an optical signal from at least one of the one or more inputs; and convey the optical signal to at least one of the one or more outputs; an optical resonator configured to modulate or filter the optical signal; and a heater configured to heat the optical resonator, the heater being line-shaped and having a first side and a second side opposite the first side, and the optical resonator comprising a first portion at the first side of the heater and a second portion at the second side of the heater.

Abstract: Devices to mitigate polarization mode dispersion are provided. An example device comprises: an input coupler configured to receive an optical signal comprising a first portion in a first polarization mode and a second portion in a second polarization mode, the second polarization mode about perpendicular to the first polarization mode; an output and/or an optical detector; and one or more optical components configured to convey the optical signal from the input coupler to the output and/or optical detector, one or more of the input coupler and the optical component(s) introducing a total differential group delay between the first and second portions. The optical component(s) comprising: a rotating component configured to rotate the first polarization mode of the first portion to the second polarization mode and rotate the second polarization mode of the second portion to the first polarization mode, to adjust the total differential group delay.

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.
