The structured film includes a polymeric substrate, an etch stop layer disposed on the polymeric substrate, a structured layer including a plurality of engineered structures disposed on a side of the etch stop layer opposite the polymeric substrate, a planarizing backfill layer disposed over the plurality of engineered structures to define a substantially planar major surface of the planarizing backfill layer having a surface roughness Ra, and an adhesive layer disposed on the substantially planar surface of the planarizing backfill layer and bonding the structured film to the waveguide. A difference in index of refraction of the planarizing backfill layer and the structured layer is at least 0.25 for at least a first wavelength W1 in a range of 400 nm to 2500 nm. The adhesive layer has an average thickness ta where Ra

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.

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: A light control film includes a two-dimensional array of projections arranged across the light control film. A square of a magnitude of a Fourier transform frequency spectrum of the projections includes a plurality of distinct peaks separated by one or more valleys. The peaks and the one or more valleys have respective averages Pavg and Vavg, Pavg/Vavg≥5, such that when light from a substantially Lambertian light source is incident on the light control film, the light control film transmits the incident light with the transmitted light propagating along a transmission axis and having an intensity profile having a full width at half maximum of less than about 120 degrees in each cross-section of the intensity profile that comprises the transmission axis.

Abstract: A structured surface reduces optical reflectance at a predetermined wavelength in a first wavelength range extending from 600 nm to 1700 nm. The structured surface includes a plurality of parallel linear structures arranged along a first direction and extending along an orthogonal second direction. Each linear structure includes opposing nonlinear facets meeting at a peak extending along the second direction. An average spacing between the peaks of adjacent linear structures is less than the predetermined wavelength, such that for light having the predetermined wavelength and incident on the structured surface in a direction substantially perpendicular to the first and second directions, the structured surface has a reflectance Rx
