    Abstract: An optical waveguide propagates an optical mode at a first wavelength along a length of the waveguide. The optical waveguide has an optical core with a substantially polygonal cross-section in a plane substantially perpendicular to the length of the waveguide. The optical core has an index of refraction n1 at the first wavelength. A first optical cladding is disposed adjacent the optical core and has an index of refraction n2 at the first wavelength, n2

    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.

    IPC: G02B6/38

    Abstract: An optical connector includes a housing with a bottom wall defining a window therein, and an optical ferrule disposed in the housing and comprising opposing major top and bottom surfaces. The major bottom surface of the optical ferrule faces the bottom wall of the housing. The major top surface includes a groove and a light redirecting surface configured to receive light along a first direction from an optical fiber received and secured in the groove, and redirect the received light along a different second direction. The redirected light exits the optical ferrule though the bottom surface and exits the housing through the window, such that, when the optical connector mates with a mating optical connector including a mating optical ferrule, the mating optical ferrule prevents any of the light exiting the optical ferrule from exiting the housing of the optical connector.

    IPC: G02B6/38

    Abstract: An optical ferrule includes at least one light affecting element configured to affect one or more characteristics of light from an optical waveguide as the light propagates in the optical ferrule, the light affecting element having an input surface. At least one receiving element receives and secures the optical waveguide to the ferrule so that an output surface of the waveguide is optically coupled to the input surface of the light affecting element. A waveguide stop limits movement of the waveguide toward the input surface of the light affecting element when the optical waveguide is installed in the receiving element. A space between the output surface of the optical waveguide and the input surface of the light affecting element is inaccessible to the optical waveguide when the optical waveguide is installed in the receiving element.

    Abstract: Solar light redirecting glazing units include light redirecting and light diffusing constructions. The solar light redirecting glazing units may include a glazing substrate, a visible light diffusing layer, and a light redirecting layer oriented such that incoming solar light contacts the visible light diffusing layer before contacting the light redirecting layer. The solar light redirecting glazing units may include a glazing substrate, a patterned visible light diffusing layer, and a light redirecting layer. The solar light redirecting glazing units may include two glazing substrates separated by an intervening space with a solar light redirecting layer disposed on one glazing substrate, and a visible light diffusing layer disposed on the other glazing substrate.

    Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

    Abstract: A taillight article (100) including an optically clear light guide (110) having an light emission front surface (112) and an opposing rear surface (114) and a side surface (118) separating the front surface (112) and the rear surface (114) is described. A first light source (120) is configured to direct light into the side surface (118) and indicate a first signal-function. A plurality of light extraction features (116) are on or within the optically clear light guide (110) and are configured to direct light from the first light source (120) out through the emission surface (112). A light reflection element (130) is spaced apart from the rear surface (114) and defines a cavity (135) that is observable by a viewer.
