Abstract: An optical device (1) includes two prism bodies (41, 42) and four side panels (71-74) attached to both prism bodies (41, 42). A cavity (9) is thereby enclosed. A first reflector (81) can be present at a first side face (81) of the first prism body (41), and a second reflector (82) can be present at a second side face (82) of the second prism body (42). At least one of the prism bodies (41, 42) and/or at least one of the side panels (71-74) can be at least in part made of a non-transparent dielectric material such as a printed circuit board. In some implementations, an optoelectronic component (90) can be attached to the respective constituent of the optical device (1).

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 apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array (L1) comprising a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array (S1) of light sources (1) for emitting light of a wavelength L each and having an aperture each, wherein the apertures are located in a common emission plane which is located at a distance D from the microlens array. For the lens pitch P, the distance D and the wavelength L, the following equation applies P2=2LD/N, wherein N is an integer with N≥1. High-contrast high-intensity light patterns can be produced. Devices comprising such apparatuses can be used for depth mapping.

Abstract: The invention relates to wafer-level manufacturing of optical devices such as modules comprising micro-lenses. In one aspect, passive optical components such as truncated lenses are manufactured by providing a substrate on which a multitude of precursor optical structures is present; and removing material from each of said multitude of precursor optical structures. Another aspect comprises a method for manufacturing a device comprising a set of at least two passive optical components, said method comprising the steps of using a tool obtained by carrying out the steps of manufacturing a precursor tool having a replication surface; and modifying said replication surface by removing material from said precursor tool. An yet another aspect comprises a method for manufacturing a device comprising a set of at least two passive optical components, wherein the method comprises the step of using a master comprising a replication surface comprising, for each of said passive optical components, a first portion describing a shape corresponding to the shape of at least a portion of the respective passive optical component, wherein the master comprises, in addition, at least one protruding portion protruding from at least one of said first portions of said replication surfaces.

Abstract: Fabricating optical devices can include mounting a plurality of singulated lens systems over a substrate, adjusting a thickness of the substrate below at least some of the lens systems to provide respective focal length corrections for the lens systems, and subsequently separating the substrate into a plurality of optical modules, each of which includes one of the lens systems mounted over a portion of the substrate. Adjusting a thickness of the substrate can include, for example, micro-machining the substrate to form respective holes below at least some of the lens systems or adding one or more layers below at least some of the lens systems so as to correct for variations in the focal lengths of the lens systems.

Abstract: The present disclosure describes optoelectronic modules (e.g., hybrid lens array packages) that have multiple optical channels, each of which includes at least one beam shaping element (e.g., a lens) that is part of a laterally contiguous array. Each optical channel is associated with a respective light sensitive region of an image sensor. Some or all of the channels also can include at least one beam shaping element (e.g., a lens) that is not part of a laterally contiguous array. In some cases, the arrays can include alignment features to facilitate alignment of the arrays with one another.
