  • Publication number: 20240096855
    Abstract: A method of wafer-level manufacturing of an optical package (285) is disclosed. The method comprises forming an apertured substrate (170; 405) by a process of vacuum injection molding, each aperture (175A; 175B) in the apertured substrate configured to support an optical element (225; 420; 425). The method also comprises coupling the apertured substrate to a further substrate (255) comprising optical devices (260, 265) aligned with the apertures in the apertured substrate. Also disclosed is optical package (285, 600) formed according to the method and an apparatus, such as a smartphone, comprising the optical package.

  • Publication number: 20220045247
    Abstract: An apparatus includes an optoelectronic module including a light emitting die and a light receiver die mounted on a PCB substrate. The optoelectronic module further includes an optical element on the light emitting die and an optical element on the light receiver die, the optical elements being composed of a first epoxy. A second epoxy laterally surrounds and is in contact with respective side surfaces of the light emitting die, the light receiver die and the optical elements, wherein the second epoxy provides an optical barrier between the light emitting die and the light receiver die. A method of manufacturing such modules is described as well.

  • Publication number: 20210041650
    Abstract: An apparatus includes an optoelectronic component mounted to a PCB substrate. A transmissive adhesive is disposed directly on the optoelectronic component and is transmissive to light of a wavelength sensed by, or emitted by, the optoelectronic component. The apparatus includes an optical filter disposed directly on the transmissive adhesive. An epoxy laterally surrounds and is in contact with side surfaces of the transmissive adhesive and the optical filter. The epoxy is non-transmissive to light of a wavelength sensed by, or emitted by, the optoelectronic component. In some cases, the epoxy defines a recess directly over the optical filter to accommodate an optical component, such as an optical diffuser. Methods of fabricating the modules are disclosed as well.

  • Patent number: 10475830
    Abstract: An optical module comprising: a plurality of active optoelectronic components each one mounted on a respective printed circuit board (PCB), wherein each active optoelectronic component is associated with a respective different optical channel; a plurality of optical assemblies, each one is substantially aligned over a different respective optical channel; and a spacer separating the active optoelectronic components and PCBs from the optical assemblies, wherein the optical assemblies are attached by adhesive directly to an optical assembly-side surface of the spacer. A first active optoelectronic component is separated, by the spacer, from a first optical assembly by a first distance and a second active optoelectronic component is separated, by the spacer, from a second optical assembly by a different second distance.

  • Patent number: 10199426
    Abstract: Various optoelectronic modules are described that include an optoelectronic device (e.g., a light emitting or light detecting element) and a transparent cover. Non-transparent material is provided on the sidewalls of the transparent cover, which, in some implementations, can help reduce light leakage from the sides of the transparent cover or can help prevent stray light from entering the module. Fabrication techniques for making the modules also are described.

  • Patent number: 10186540
    Abstract: Optoelectronic modules include an optoelectronic device and a transparent cover. A non-transparent material is provided on the sidewalls of the transparent cover, which can help reduce light leakage from the sides of the transparent cover or can help reduce stray light from entering the module. The modules can be fabricated, for example, in wafer-level processes. In some implementations, openings such as trenches are formed in a transparent wafer. The trenches then can be filled with a non-transparent material using, for example, a vacuum injection tool. When a wafer-stack including the trench-filled transparent wafer subsequently is separated into individual modules, the result is that each module can include a transparent cover having sidewalls that are covered by the non-transparent material.
