Abstract: An optical device may include a lens system. The optical device may include a first scanning component to receive an optical beam and to scan the lens system with the optical beam. The optical device may include a second scanning component to receive the optical beam from the lens system and to scan a field of view with the optical beam, where the lens system is positioned between the first scanning component and the second scanning component. The lens system may include a beam expander.

Abstract: An optical device may include a package having a first port for receiving signal light, a source for providing pump light, a combiner for combining the signal light and the pump light into combined light, a second port for sending the combined light, a third port for receiving amplified light, and a free-space optical system for filtering amplified signal light from the amplified light, and a fourth port for sending the amplified signal light. The free-space optical system may include beam shaping optics that enlarge a beam size of the amplified light prior to the filtering.

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 Mach-Zehnder interferometer (MZI) includes a delay line arm formed in a chip and a mirrored facet formed in the chip. The delay line arm may be configured to propagate light to the mirrored facet. The mirrored facet may be configured to reflect, to the delay line arm, a percentage of the light propagated to the mirrored facet by the delay line arm.
