Abstract: An optoelectronic apparatus includes a semiconductor substrate and an array of emitters disposed on the semiconductor substrate and configured to emit beams of optical radiation having respective chief rays. An optical diffuser is mounted over the semiconductor substrate and configured to diffuse the beams. Microlenses are disposed between the semiconductor substrate and the optical diffuser in respective alignment with the emitters and configured to steer the beams at different, respective angles, which are selected so that at least some of the chief rays cross one another before passing through the diffuser.

Abstract: An optoelectronic apparatus includes a heat sink, which is shaped to define a base, a first platform at a first elevation above the base, and a second platform alongside the first platform at a second elevation above the base, which is different from the first elevation. A first monolithic emitter array is mounted on the first platform and is configured to emit first optical beams. A second monolithic emitter array is mounted on the second platform and is configured to emit second optical beams. An optical element is configured to direct both the first and the second optical beams toward a target region.

Abstract: An optoelectronic apparatus includes a semiconductor substrate and multiple arrays of emitters disposed on the semiconductor substrate and configured to emit beams of optical radiation. An optical substrate is mounted over the semiconductor substrate. An optical metasurface disposed on the optical substrate includes multiple optical apertures. Each aperture is configured to receive, collimate and split the beams emitted by a respective array of the emitters into a respective group of collimated sub-beams, so as to direct the collimated sub-beams toward a target at different, respective angles to form a pattern of spots on the target.

Abstract: Various embodiments disclosed herein include devices, systems, and methods for spatially controlling illumination provided by a flash module. The flash module includes a flash controller that controls light emitters of an emitter array according to an illumination profile. The illumination profile is selected to reduce a relative brightness to a target region of the flash module's field of illumination. The target region is associated with a portion of a target object identified in the field of illumination. In some instances, the target region corresponds to a portion of a user's eye that is positioned within the field of illumination. In other instances, the flash module is incorporated into a device, and the target region corresponds to a reflected image of a portion of the device that is positioned within the field of illumination.

Abstract: An optoelectronic apparatus includes a substrate and first and second arrays of emitters disposed on the substrate and configured to emit respective first and second beams of optical radiation. The apparatus further includes an optical metasurface disposed on the substrate and configured to collimate and diffuse the first beams without diffusing the second beams, and an optical projection element, configured to intercept both the first and the second beams that have passed through the optical metasurface and to direct both the first and the second beams toward a target while focusing the second beams to form a pattern of spots on the target.

Abstract: A compact folded projection system is described that includes a laser light source, a folded lens system comprising a lens stack including two or more refractive lenses and a light folding element (e.g., a prism), and a diffractive beam splitter that includes at least one diffractive surface. The light folding element provides a “folded” optical axis for the lens system to reduce the Z-height of the projection system, for example to within a range of 1.7 to 4 millimeters (e.g., 2 millimeters in some implementations). The laser light source emits light that is refracted by the lens stack to the folding element. The folding element redirects the light to the beam splitter which replicates the light into N×M duplications or tiles to thus generate a larger field of view (FOV) than the internal FOV of the lens system.

Abstract: An optical apparatus includes a transparent envelope having opposing first and second faces. An electro-optic material is contained within the transparent envelope and includes molecules oriented in respective predefined directions selected so as to form a geometric-phase structure across an area of the transparent envelope. First and second transparent electrodes are disposed respectively across the first and second faces of the transparent envelope. A controller is coupled to apply a voltage between the first and second transparent electrodes that is sufficient to displace the molecules of the electro-optic material from the predefined directions.
