    摘要: 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.

    摘要: 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.

    摘要: 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.
