Abstract: An optical device may include a laser component to emit a source beam and an optical component to split the source beam to generate a first beam and a second beam. The optical device may include a multiplexing component to multiplex the first beam and the second beam to form a first multiplexed beam, an optical system to receive the first multiplexed beam and demultiplex the first beam and the second beam, and a scanning component to scan a field of view with the first beam and the second beam and receive the first beam and the second beam reflected from the field of view. The optical system may multiplex the first beam and the second beam reflected from the field of view to form a second multiplexed beam, and a demultiplexing component may demultiplex the first beam and the second beam reflected from the field of view.

Abstract: In some implementations, a thermally-controlled photonic structure may include a suspended region that is suspended over a substrate; a plurality of bridge elements connected to the suspended region and configured to suspend the suspended region over the substrate, where a plurality of openings are defined between the plurality of bridge elements; and at least one heater element having a modulated width disposed on the suspended region. The at least one heater element having the modulated width may include at least one section of a greater width and at least one section of a lesser width. The at least one section of the greater width may be in alignment with an opening of the plurality of openings and the at least one section of the lesser width may be in alignment with a bridge element of the plurality of bridge elements.

Abstract: A device may include a first photodetector to generate a first current based on an optical power of an optical beam. The device may include a beam splitter to split a portion of the optical beam into a first beam and a second beam. The device may include a wavelength filter to filter the first beam and the second beam. The wavelength filter may filter the second beam differently than the first beam based on a difference between an optical path length of the first beam and an optical path length of the second beam through the wavelength filter. The device may include second and third photodetectors to respectively receive, after the wavelength filter, the first beam and the second beam and to generate respective second currents.
