Abstract: An OLED display including a display panel and a color-correction component is described. A plurality of comparative display panels otherwise equivalent to the display panel but having one or more different optical thicknesses of OLED layers have a maximum white-point color shift from 0 to 45 degrees of WPCSC45 and a white-point axial efficiency of WPAEC. The plurality of comparative display panels defines a performance curve along a boundary of performance points. The OLED display and the display panel have respective maximum white-point color shifts from 0 to 45 degrees of WPCS45 and WPCS045 and respective white-point axial efficiencies of WPAE and WPAE0. WPCS045 and WPAE0 defines a performance point of the display panel to the right of the performance curve and WPCS45 and WPAE defines a performance point of the OLED display above or to the left of the performance curve. Methods of making the OLED display are described.

Abstract: An optical connector assembly (100) includes a housing (110), an optical ferrule (140); and an optical fiber array (150). The housing (110) has a mating end (111) and an opposite cable end (112) and includes: a first housing portion (120) including a front support (122) proximate the mating end (111) and a rear support (124) disposed between the front support (122) and the cable end (112); and a second housing portion (130) assembled to the first housing portion (120) and including a middle support (133) disposed between the front and rear supports (122,124). The ferrule (140) is supported by the front support (122). Front ends of optical fibers of the optical fiber array (150) are received by and attached to an attachment area of the ferrule (140). When the second housing portion (130) is assembled to the first housing portion (120), the middle support (133) of the second housing portion (130) contacts and bends the optical fiber array (150) about the middle support (133). The bend causes the optical ferrule (140) to rotate about the front support (122).

Abstract: A light coupling element including a groove and a light redirecting member is described. The groove is for receiving and aligning an optical waveguide and incudes an open front end and a back end. The light redirecting member includes an input side for receiving light from an optical waveguide received and supported in the groove and a light redirecting side for changing a direction of light received from the input side. The groove may include a bottom surface extending between the front and back ends of the groove and including a raised bottom surface portion raised upwardly relative to an unraised bottom surface portion. The unraised bottom surface portion of the bottom surface may be disposed between the raised bottom surface portion of the bottom surface and the input side of the light redirecting member. Optical coupling assemblies including the light coupling element and an optical waveguide are described.

Abstract: Metallic nanohole (23) arrays on nanowells (22) with a controlled depth and methods of making and using the same are provided. A mesh pattern of metallic layer (8) having an array of nanoholes is provided on an array of nanowells, aligned with the openings of the respective nanowells. The aspect ratios (D:W) of the nanowells are controlled to control the deposition of metal into the nanowells.

Abstract: An optical construction includes a lens layer and optically opaque first and second mask layers. The lens layer has a first major surface including a plurality of microlenses arranged along orthogonal first and second directions. The first and second mask layers are spaced apart from the first major surface and define respective pluralities of through first and second openings therein arranged along the first and second directions. The first mask layer is disposed between the structured first major surface and the second mask layer. There is a one-to-one correspondence between the microlenses and the first and second openings. The optical construction includes an intermediate layer disposed between the structured first major surface and the first mask layer and including an undulating second major surface facing, and in substantial registration with, an undulating third major surface of first mask layer so as to define a substantially uniform spacing therebetween.

Abstract: An optical combiner includes a first layer with a periodic two-dimensional arrangement of structures arranged to support resonance for an input signal of a target wavelength, wherein the structures have a first refractive index. A second layer overlies the structures on the first layer, wherein the second layer includes a second material with a second refractive index, and wherein a difference between the first refractive index and the second refractive index, measured at 587.5 nm, is less than about 1.5. The periodic arrangement of structures is configured such that the optical combiner produces, for the input signal incident on the first layer from air at an oblique elevation angle of greater than about 20°, an output signal with a reflection peak with an average reflection of greater than about 50% within a ± 5° range of the elevation angle.

Abstract: An inspection device for an optical ferrule includes one or more reflectors. Each reflector has a mating surface and a mirror disposed at an oblique angle with respect to the mating surface. Each reflector is configured to mate with the optical ferrule when the optical ferrule is disposed within a housing of an optical connector. When the mating surface of the reflector is in mated contact with the mating surface of the optical ferrule, the mirror is positioned to provide a reflected view of at least a portion of a mating surface of the optical ferrule.
