Abstract: Described herein are one or more methods for integrating an optical component into an integrated photonics device. The die including a light source, an outcoupler, or both, may be bonded to a wafer having a cavity. The die can be encapsulated using an insulating material, such as an overmold, that surrounds its edges. Another (or the same) insulating material can surround conductive posts. Portions of the die, the overmold, and optionally, the conductive posts can be removed using a grinding and polishing process to create a planar top surface. The planar top surface enables flip-chip bonding and an improved connection to a heat sink. The process can continue with forming one or more additional conductive layers and/or insulating layers and electrically connecting the p-side and n-side contacts of the laser to a source.

Abstract: This disclosure relates to an integrated thermoelectric cooler and methods for forming thereof. The integrated thermoelectric cooler can include a plurality of thermoelectric rods located between the detector substrate and a system interposer. The detector substrate and the system interposer can directly contact ends of the thermoelectric rods. The integrated thermoelectric cooler can be formed by forming the plurality of thermoelectric rods on reels, for example, and the plurality of thermoelectric rods can be thinned down to a certain height. The thermoelectric rods can be transferred and bonded to the system substrate. An overmold can be formed around the plurality of thermoelectric rods. The height of the overmold and thermoelectric rods can be thinned down to another height. The thermoelectric rods can be bonded to the detector substrate. In some examples, the overmold can be removed.

Abstract: Described herein is an integrated photonics device including a light emitter, integrated edge outcoupler(s), optics, and a detector array. The device can include a hermetically sealed enclosure. The hermetic seal can reduce the amount of moisture and/or contamination that may affect the measurement, analysis, and/or the function of the individual components within the sealed enclosure. Additionally or alternatively, the hermetic seal can be used to protect the components within the enclosure from environmental contamination induced during the manufacturing, packaging, and/or shipping process. The outcoupler(s) can be formed by creating one or more pockets in the layers of a die. Outcoupler material can be formed in the pocket and, optionally, subsequent layers can be deposited on top. The edge of the die can be polished until a targeted polish plane is achieved. Once the outcoupler is formed, the die can be flipped over and other components can be formed.

Abstract: An integrated photonics device that emits light out towards a measured sample value is disclosed. The device can include a discrete optical unit that attaches to a supporting layer. The discrete optical unit can include mirror(s), optics, detector array(s), and traces. The supporting layer can include one or more cavities having facet walls. Light emitter(s) can emit light that propagate through waveguide(s). The emitted light can exit the waveguide(s) (via termination point(s)), enter the one or more cavities at the facet walls, and be received by receiving facets of the discrete optical unit. The mirror(s) of the discrete optical unit can redirect the received light towards collimating optics, which can direct the light out of the device through the system interface. The discrete optical unit can be formed separately from the supporting layer or bonded to the supporting layer after the mirror, optics, detector arrays, and traces are formed.

Abstract: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

Abstract: This relates to sensor systems, detectors, imagers, and readout integrated circuits (ROICs) configured to selectively detect one or more frequencies or polarizations of light, capable of operating with a wide dynamic range, or any combination thereof. In some examples, the detector can include one or more light absorbers; the patterns and/or properties of a light absorber can be configured based on the desired measurement wavelength range and/or polarization direction. In some examples, the detector can comprise a plurality of at least partially overlapping light absorbers for enhanced dynamic range detection. In some examples, the detector can be capable of electrostatic tuning for one or more flux levels by varying the response time or sensitivity to account for various flux levels. In some examples, the ROIC can be capable of dynamically adjusting at least one of the frame rate integrating capacitance, and power of the illumination source.
