Abstract: Compact optoelectronic modules are described that, in some implementations, can have reduced heights, while at the same time having very little optical crosstalk or detection of stray light. An optoelectronic module having optical channel can include a support on which is mounted an optoelectronic device arranged to emit or detect light at a particular one or more wavelengths. The module has a cover including an optically transmissive portion over the optoelectronic device. The optically transmissive portion is surrounded laterally by sections of the cover that are substantially non-transparent to the one or more wavelengths. A passive optical element is present on a surface of the optically transmissive portion. A spacer separates the support from the cover. The cover can be relatively thin so that the overall height of the module is relatively small.

Abstract: The present disclosure describes proximity sensor modules that include a time-of-flight (TOF) sensor. The module can include a plurality of chambers corresponding, respectively, to a light emission channel and a light detection channel. The channels can be optically separated from one another such that light from a light emitter element in the light emission chamber does not impinge directly on light sensitive elements of the TOF sensor in the light detection chamber. To achieve a module with a relatively small footprint, some parts of the TOF sensor can be located within the light emission chamber.

Abstract: An optoelectronic module includes a transceiver operable to transmit data optically. The transceiver includes a light emitter to emit light from the module, and a light detector to detect light entering the module. The light detector is disposed at a rotationally symmetric position with respect to a central axis of the module. Such modules can help facilitate the exchange of data optically between two devices.

Abstract: An optical proximity sensor module includes a substrate, a light emitter mounted on a first surface of the substrate, the light emitter being operable to emit light at a first wavelength, and a light detector mounted on the first surface of the substrate, the light detector being operable to detect light at the first wavelength. The module includes an optics member disposed substantially parallel to the substrate, and a separation member, wherein the separation member is disposed between the substrate and the optics member. Multiple modules can be fabricated in a wafer-level process and can be composed of reflowable materials so that the modules can be incorporated more easily into devices whose manufacture occurs, at least in part, at elevated temperatures when the module is integrated into the device or during subsequent manufacturing processes.

Abstract: Time-of-flight (TOF) based systems using light pulse compression are described and, in some cases, can help increase demodulation contrast. Further, light pulse shaping techniques are described that, in some cases, can help reduce phase non-linearity and distance-calculation errors. The techniques can be used, for example, in measurement systems, as well as imaging systems in which a time-of-flight and/or distance information is obtained. The time-of-flight and/or distance information can be used to reconstruct and display a three-dimensional image of a scene. The light compression techniques also can be used to provide reference signals.
