    Abstract: Optoelectronic apparatus includes a projector, which includes an array of first emitters, which emit respective first beams of optical radiation at a first wavelength, and a second emitter, which emits a second beam of optical radiation at a second wavelength. Projection optics receive the first and second beams of the optical radiation through an entrance face and project the beams through the exit face. An optical window transmits the radiation at the first wavelength and reflects the radiation at the second wavelength, and is positioned adjacent to the exit face of the projection optics so as to reflect the second beam back through the projection optics toward an optical sensor positioned in proximity to the first and second emitters. A controller drives an actuator to adjust a focal setting of the projection optics responsively to a distribution of the optical radiation received and sensed by the optical sensor.

    Abstract: An optoelectronic apparatus includes an array of emitters configured to emit respective beams of optical radiation. Projection optics include first cylindrical lenses, which have respective, mutually-parallel first cylinder axes, and are aligned respectively with the emitters in the array so as to receive and project the respective beams, and a second cylindrical lens, which has a second cylinder axis perpendicular to the first cylinder axes and is positioned adjacent to the first cylindrical lenses so as to receive and project all of the beams from the first cylindrical lenses.

    Abstract: A method for production of an optoelectronic device includes fabricating a plurality of vertical emitters on a semiconductor substrate. Respective top surfaces of the emitters are bonded to a heat sink, after which the semiconductor substrate is removed below respective bottom surfaces of the emitters. Both anode and cathode contacts are attached to the bottom surfaces so as to drive the emitters to emit light from the bottom surfaces. In another embodiment, the upper surface of a semiconductor substrate is bonded to a carrier substrate having through-holes that are aligned with respective top surfaces of the emitters, after which the semiconductor substrate is removed below respective bottom surfaces of the emitters, and the respective bottom surfaces of the emitters are bonded to a heat sink.

    Abstract: Optical apparatus includes a plurality of emitters arranged in a row and configured to emit respective beams of optical radiation. Projection optics, which are configured to project the beams toward a target, include first cylindrical lenses, which have respective, mutually-parallel first cylinder axes and are aligned respectively with the emitters in the row so as to receive and focus the respective beams in a first dimension, and a second cylindrical lens, which has a second cylinder axis perpendicular to the first cylinder axes and is positioned to receive and focus all of the beams in a second dimension, perpendicular to the first dimension. A scan driver is configured to shift the second cylindrical lens in a direction perpendicular to the second cylinder axis so as to scan the beams across the target.
