    Abstract: Various embodiments disclosed herein describe optomechanical phase shifters. The optomechanical phase shifters may be configured with an asymmetry that improves the performance of the OM phase shifter as a function of wavelength. In some instances, the optomechanical phase shifter includes a section of a waveguide having an asymmetric cross-sectional shape. In other instances an optomechanical phase shifter is incorporated into a controllable optical switch, such that OM phase shifters may be actuated to selectively route light to different outputs of the controllable optical switch.

    Abstract: A photonic integrated circuit as discussed herein may include one or more multimode waveguide interfaces that define a corresponding transition between a waveguide and a free propagation region of a photonic integrated circuit. Specifically, a multimode waveguide interface may include an input waveguide that is connected to an interferometric waveguide, and a slab waveguide connected to the interferometric waveguide. The input waveguide and interferometric waveguide are positioned and configured to convert a portion of a first mode of light into a second mode of light, such that the first and second modes interfere within the interferometric waveguide. The interferometric waveguide is configured such that these modes are in phase for a first target wavelength and out of phase for a second target wavelength at an interface between the interferometric waveguide and the slab waveguide.

    Abstract: Configurations for an optical splitter that includes a continuous curved reflector and methods thereof are disclosed. The optical splitter includes an input waveguide, one or more continuous curved reflector, and multiple output waveguides. The one or more continuous curved reflector may direct light toward the output waveguides. The optical splitter may include a single continuous curved reflector, or may include multiple continuous curved reflectors. In other instances, an optical splitter may include a lensed reflector that includes a plurality of continuous curved segments.

    Abstract: Embodiments are directed to optical measurement systems that utilize multiple emitters to emit light during a measurement, as well as methods of performing measurements using these optical measurement systems. The optical measurement systems may include a light generation assembly that is configured to generate light via a light source unit, and a photonic integrated circuit that includes a launch group having a plurality of emitters. Each of these emitters is optically coupled to the light generation assembly to receive light generated from the light generation assembly, and may emit this light from a surface of the photonic integrated circuit. The optical measurement system may perform a measurement in which the light generation assembly generates light and each of the plurality of emitters simultaneously emit light received from the light generation assembly.

    Abstract: Various embodiments disclosed herein describe photonic passive delay lines that have a waveguide wound into a plurality of straight segments and bends. The photonic passive delay lines are configured to reduce losses from parasitic modes of light generated at the bends. Embodiments of the photonic passive delay lines vary the dimensions of the straight segments to provide different amounts of dephasing between a mode of input light received by the photonic passive delay line and one or more parasitic modes.
