    Abstract: The disclosure generally relates to individual optical waveguides, sets of optical waveguides such as optical fiber ribbons, and fiber optic connectors useful for connecting individual optical waveguides or multiple optical fibers such as in optical fiber ribbon cables. In particular, the disclosure provides an efficient, compact, and reliable optical fiber connector that exhibits a low insertion loss for use with multimode optical waveguides. The optical connectors incorporate a unitary light coupling unit combining the features of optical fiber alignment, along with redirecting and shaping of the optical beam.

    Abstract: Illumination articles are described. More specifically, illumination articles that include a wearable device configured for wearing on the head of a wearer, a lightguide and light sources for emitting light into the lightguide are described. The illumination articles allow for wearable devices that uniformly illuminate a working area at high brightness without providing excessive glare to observers. The disclosed illumination article comprises: a wearable device configured for wearing on the head of a wearer, a lightguide disposed on the wearable device, wherein the lightguide is elongated and has a first end and a second end opposite the first end, and a first light source positioned at the first end, for emitting light into the lightguide. The lightguide further comprises a light emitting surface extending generally in an x-direction between the first and second end, and a light reflecting surface positioned opposite to the light emitting surface, wherein the light reflecting surface comprises a plurality of light extractors configured for directing light in a y-direction perpendicular to the x-direction, and wherein the light emitting surface is configured for directing light into an xy-plane.

    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.
