Abstract: A structured film for forming a pattern on a substrate includes a polymeric support layer, an adhesive layer, an etch resist layer disposed between the polymeric support layer and the adhesive layer, a structured resin layer disposed between the polymeric support layer and the etch resist layer, and one or more unstructured layers disposed between the etch resist layer and the adhesive layer. The structured resin layer has a structured major surface including a plurality of engineered structures. The etch resist layer at least partially fills spaces between adjacent engineered structures to substantially planarize the structured major surface. Methods of using the structured film to form a pattern on a substrate are described.

Abstract: A unitary optical ferrule is molded to include one or more elements for receiving and securing one or more optical waveguides one or more elements for affecting one or more characteristics of light from the optical waveguide while propagating the light within the ferrule. The optical ferrule also includes one or more first alignment features and one or more second alignment features that, when the ferrule is mated with a mating ferrule, each controls alignment of the ferrule with the mating ferrule along three mechanical degrees of freedom. The surface of the optical ferrule can be divided along the thickness axis into a first section and an opposing second section, wherein the first section of the surface includes the receiving and securing elements, the light affecting elements, and the first alignment features and the second section of the surface includes the second alignment features.

Abstract: Nanostructured articles, materials for the nanostructured articles, and intermediate articles for use in making the nanostructured articles. The nanostructured articles can be formed on a flexible film and are useful for optical metasurface applications and possibly other applications. The articles can include nanoreplicated layers or pattern transfer layers of engineered nanostructures.

Abstract: An optical ferrule (200) has opposing major top (10) and bottom (20) surfaces where the bottom surface includes discrete spaced apart first (90) and second (100) platforms arranged along a mating direction of the optical ferrule (200). During a mating of the ferrule (200) with a mating optical ferrule (200′), the first (90) and second (100) platforms of the ferrule (200) slide against corresponding respective first (90′) and second (100′) platforms of the mating ferrule (200′). Upon full mating of the ferrule (200) with the mating ferrule (200′), the second platforms (100, 100′) of the ferrule and the mating ferrule remain in contact with and rest on each other, and the first platform (90, 90′) of neither ferrule makes contact with the other ferrule.

Abstract: An emissive article includes an OLED having a light emission surface, a circular polarizer, and a light extraction film optically between the OLED and the circular polarizer and being optically coupled to the light emission surface. The light extraction film includes a two-dimensional structured layer of extraction elements having a first index of refraction and a pitch in a range from 400 to 800 nm and a backfill layer including a material having a second index of refraction different from the first index of refraction.

Abstract: A hybrid connector includes a connector housing, one or more first connection elements configured to transfer a first type of energy or a fluid, and one or more second connection elements configured to transfer a second type of energy, different from the first type of energy, or the fluid. The first connection elements are rotationally fixed and the second connection elements are configured to rotate around an axis that is substantially perpendicular to a mating axis of the housing.

Abstract: Provided are methods and associated compositions directed to a structural bonding adhesive. The structural bonding adhesive is made by mixing a curable composition comprising a mixture of a first curable resin and a second curable resin to provide an uncured adhesive. The uncured adhesive is irradiated by a first actinic light source to polymerize the first curable resin without polymerizing the second curable resin to provide a partially cured adhesive. The partially cured adhesive is a pressure-sensitive adhesive that displays cold flow creep recovery under ambient conditions and is capable of being fully cured by irradiating the partially cured adhesive using a second actinic light source that is different from the first actinic light source to polymerize the second curable resin.

Abstract: An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.
