Abstract: Various stacks of arrays of beam shaping elements are described. Each array of beam shaping elements can be formed, for example, as part of a monolithic piece that includes a body portion as well as the beam shaping elements. In some implementations, the monolithic pieces may be formed, for example, as integrally formed molded pieces. The monolithic pieces can include one or more features to facilitate stacking, aligning and/or centering of the arrays with respect to one another.

Abstract: A time of flight-based system is operable for ambient light measurements. A method of operation includes detecting, in at least one active demodulation detection pixel, a first particular wavelength and generating amplitude data of the first particular wavelength; and detecting, in at least one spurious reflection detection pixel, a second particular wavelength and generating amplitude data of the second particular wavelength. In a computational device that stores spectrum data corresponding respectively to a plurality of different ambient light source types, an ambient lighting condition is determined based on the amplitude data of the first particular wavelength, the amplitude data of the second particular wavelength and the spectrum data of a particular one of the ambient light source types associated with the amplitude data of the first particular wavelength and the amplitude data of the second particular wavelength.

Abstract: A lens module includes a substrate, a first array of passive optical elements on the substrate, and a second array of passive optical elements separate from the first array. The optical elements of the first array and the optical elements of the second array form multiple optical channels, in which at least one optical channel is a catadioptric optical channel including a reflective optical element and a refractive optical element. The reflective optical element is arranged to reflect light toward the refractive optical element, each optical channel has a corresponding field-of-view, and the lens module has an overall field of view defined by the range of angles subtended by the field-of-view of the plurality of optical channels.

Abstract: The present disclosure describes light conversion modules each having a single laser diode or multiple laser diodes. The light conversion modules can be particularly small in size (height and lateral footprint) and can overcome various challenges associated with the high optical power and heat emitted by laser diodes. In some implementations, the light conversion modules include glass phosphors, which, in some instances, can resist degradation caused by the optical power and/or heat generated by the laser diodes. In some instances, the light conversion modules include optical filters which, in some instances, can reduce or eliminate human eye-safety risk.

Abstract: This disclosure describes various modules that can provide ultra-precise and stable packaging for an optoelectronic device such as a light emitter or light detector. The modules include vertical alignment features that can be machined, as needed, during fabrication of the modules, to establish a precise distance between the optoelectronic device and an optical element or optical assembly disposed over the optoelectronic device.

Abstract: An optoelectronic module includes a light guide arranged to receive light, such as ambient light or light reflected by an object. The light guide has a diffractive grating that includes multiple sections, each of which is tuned to a respective wavelength or narrow band of wavelengths. The module further includes multiple photosensitive elements, each of which is arranged to receive light diffracted by a respective one of the sections of the diffractive grating. The module can be integrated, for example, as part of a spectrometer or other apparatus for optically determining characteristics of an object.

Abstract: Various optoelectronic modules are described and include one or more optoelectronic devices. Each optoelectronic module includes one or more optoelectronic devices. Sidewalls laterally surround each optoelectronic device and can be in direct contact with sides of the optoelectronic device or, in some cases, with an overmold surrounding the optoelectronic device. The sidewalls can be composed, for example, of a vacuum injected material that is non-transparent to light emitted by or detectable by the optoelectronic device. The module also includes a passive optical element. Depending on the implementation, the passive optical element can be on a cover for the module, directly on a top surface of the optoelectronic device, or on an overmold surrounding the optoelectronic device. Methods of fabricating such modules are described as well, and can facilitate manufacturing the modules using wafer-level processes.

Abstract: The present disclosure describes modules operable to perform optical sensing. The module can be operable to distinguish between signals indicative of reflections from an object or interest and signals indicative of a spurious reflection such as from a smudge (i.e., a blurred or smeared mark) on the host device's cover glass. Signals assigned to reflections from the object of interest can be used to for various purposes, depending on the application (e.g., determining an object's proximity, a person's heart rate or a person's blood oxygen level).

Abstract: A wafer-level method of fabricating optoelectronic modules performing a first vacuum injection technique, using a first vacuum injection tool, to surround optoelectronic devices laterally with a transparent overmold region, performing a replication technique to form a respective passive optical element on a top surface of each overmold region, and performing a second vacuum injected technique to form sidewalls laterally surrounding and in contact with sides of each overmold region. The replication technique and the second vacuum injection technique are performed using a combined replication and vacuum injection tool.
