Abstract: An optical emitter device includes an emitter array comprising a plurality of end-fire tapers, each end-fire taper configured to selectively emit a respective beam of light. A lens system is configured to shape and direct each beam of light based on a position of the respective end-fire taper relative to an optical axis of the lens system. A rotating reflector, including an axis of rotation perpendicular to the optical axis of the lens system, is configured to redirect and scan the beams of light through a scanning range.

Abstract: In an optical emitter device, when point emitters are placed on the focal plane of a lens system, each individual point emitter will point to a specific free space angle depending on the position of the point emitter relative to the longitudinal central axis of the lens system. Point emitters comprising end-fire tapers combined with both a turning mirror and a micro-lens provide improved performance, because, unlike grating couplers, end-fire tapers enable uniform broadband operation with all possible polarization states. A turning mirror may be added to direct the light emission from the end-fire tapers to vertically upwards, which enables both a two-dimensional point emitter array and a more streamlined assembly process.

Abstract: Techniques for creating a replacement for optical elements with diffractive planar components based on metasurfaces are provided. In one example, a substantially flat optical component for lensing incoming electromagnetic radiation having at least one wavelength and a first phase into outgoing electromagnetic radiation having a second phase is provided.

Abstract: Disclosed are integrated photonics systems including a coupling strategy to couple light in and out of optoelectronic flip-chips bonded to a photonics chip. The refined tolerances for flip-chip assembly and angled facets defined on both chips at optical couplings improve optical performance.
