Abstract: An optical device (20A, 20B, 100, 200, 800) includes a first array of emitters (28A, 28B) disposed on a semiconductor substrate (218) and configured to emit respective beams of optical radiation. A second array (36A, 36B, 224, 808) of micro-optics (34A, 34B, 226, 802) is positioned in alignment with the respective beams of the optical emitters and arranged to condition phases of the beams so that different ones of the beams are transmitted with different phase qualities

Abstract: Sensing apparatus includes a transparent window and a LiDAR assembly, including a beam source, which is configured to emit one or more beams of optical radiation along a beam axis, and which is configured to scan the one or more beams over an angular range about the beam axis. A diffractive structure is mounted approximately parallel to the transparent window and positioned to intercept the one or more beams emitted by the LiDAR assembly and turn the beam axis to pass through the transparent window at an angle greater than 30° relative to a normal to a surface of the transparent window.

Abstract: A laser system includes a master oscillator, which emits a train of optical seed pulses with variable intervals between the pulses. An optical power amplifier includes an optical gain medium, which receives and amplifies the optical seed pulses from the master oscillator, and a pump, which applies pump radiation to the optical gain medium. A pulse generator applies a control input to the master oscillator, which causes the intervals between the optical seed pulses to vary by at least 50% at a rate of change that is greater than a response frequency of the optical gain medium. A control unit drives the pump responsively to predicted intervals between the optical seed pulses, at a variable pump power selected so that the pulse amplitudes of the output pulses vary by no more than 20% irrespective of the varying intervals between the optical seed pulses.

Abstract: An optical device includes a transmitter, which emits a beam of optical radiation, and a receiver, which includes a detector configured to output a signal in response to the optical radiation. An active area of the detector has a first dimension along a first axis and a second dimension, which is less than the first dimension, along a second axis perpendicular to the first axis. An anamorphic lens, which collects and focuses the optical radiation onto the active area of the detector, has a first focal length in a first plane containing the first axis and a second focal length, greater than the first focal length, in a second plane containing the second axis. A scanner scans the beam across a target scene in a scan direction that is aligned with the first axis, and directs the optical radiation that is reflected from the target scene toward the receiver.

Abstract: An optoelectronic device includes a silicon substrate, with a silicon waveguide layer disposed over the silicon substrate and including an optical waveguide. One or more through-silicon vias (TSVs) extend through the silicon substrate and contact the silicon waveguide layer. A III-V base layer is disposed over the silicon waveguide layer, and an optical amplifier is disposed on the III-V base layer and optically coupled to the optical waveguide.

Abstract: An optoelectronic device includes a semiconductor substrate and a vertical-cavity surface-emitting laser (VCSEL) light source formed on the substrate and configured to emit coherent light at a predefined wavelength along a beam axis perpendicular to a surface of the substrate. A block of a transparent material is mounted on the surface of the substrate and forms, with the VCSEL, a resonant cavity at the predefined wavelength having an entrance face that is aligned with the beam axis and an exit face that is laterally displaced with respect to the entrance face along a cavity axis running parallel to the surface of the substrate.

Abstract: An apparatus for driving and position sensing in a comb-drive actuator includes a generator, a driver circuit, sensing circuitry, and signal processing circuitry. The generator is configured to apply a sensing-voltage to a first electrode of the comb-drive actuator. The driver circuit is configured to apply a drive-voltage to a second electrode of the comb-drive actuator, having an opposite polarity relative to the first electrode. The sensing circuitry is configured to measure at the second electrode a sensed-waveform resulting from the sensing-voltage applied to the first electrode. The signal processing circuitry is configured to estimate a position of the first electrode relative to the second electrode based on the sensed-waveform.

Abstract: An optoelectronic device includes a substrate, having a recess formed therein. An optical isolator is mounted in the recess. A laser includes a stack of epitaxial layers on the substrate and emits a beam of radiation toward the recess along a direction parallel to a surface of the substrate. A waveguide directs the beam emitted by the laser into the optical isolator.
