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: A proximity sensor includes a light source configured to emit a beam of optical radiation and a detector configured to output an electrical signal in response to the optical radiation that is incident on the detector. A first optical multimode fiber is configured to receive the emitted beam and to direct the emitted beam toward an object. A second optical multimode fiber is configured to receive the optical radiation reflected from the object and to convey the received optical radiation to the detector. A processor is coupled to process the electrical signal so as to compute a distance to the object.

Abstract: An electronic module includes a circuit substrate including conductive pads interconnected by traces, including a ground pad for connection to an electrical ground. One or more electronic components are mounted on the circuit substrate. A housing including a dielectric material is mounted on the circuit substrate so as to cover the one or more electronic components. A metal lead, which has first and second ends, is embedded in the dielectric material such that the first end contacts the ground pad on the circuit substrate when the housing is mounted on the circuit substrate, and the second end is exposed at an outer surface of the dielectric material. A conductive coating is disposed over the outer surface of the housing in galvanic contact with the exposed second end of the metal lead.

Abstract: An apparatus for testing diffraction or diffusion of a light beam is provided. The apparatus includes a photosensitive semiconductor, shaped to define an aperture. At least one anode, and a plurality of cathodes, are coupled to the semiconductor. An optical element, configured to modify an angular spread of a light beam that traverses the optical element, is disposed within the aperture. A detector is configured to detect electric currents that pass between the cathodes and the anode in response to a portion of the light beam exiting the optical element and hitting the semiconductor. Other embodiments are also described.

Abstract: An optical module includes a transparent substrate and a refractive optical element mounted on the substrate. A conductive heating trace is deposited on the substrate around the refractive optical element. A temperature sensor senses a temperature of the substrate. Control circuitry is coupled to the temperature sensor so as to measure a difference between the temperature of the substrate and a target operating temperature of the module, and to drive a current through the conductive heating trace, responsively to the difference, so as to heat the substrate to the target operating temperature.
