Abstract: Lighting units include a light source, a light-diffusing optical fiber assembly, and a support substrate. The light-diffusing optical fiber assembly includes a plurality of light-diffusing optical fibers that are arranged in a bundled portion surrounded by a jacket and a splayed portion free from the jacket. The plurality of light-diffusing optical fibers in the splayed portion scatter light optically coupled into the plurality of light-diffusing optical fibers from the light source. The plurality of light-diffusing optical fibers within the splayed portion are structurally coupled to the support substrate.

Abstract: A method including the steps of providing a light-diffusing optical fiber (12a) having a glass core (20), a cladding (40) surrounding the core (20), and a plurality of nano-sized structures in the form of voids (32) situated within said core (20) or at a core-cladding boundary; cleaving the light-diffusing fiber (12a), thereby forming a cleaved end face (66); and applying energy to one or more of 1) the cleaved end face (66) and 2) the light-diffusing fiber (12b) along a portion of the length thereof adjacent the cleaved end face (66), the amount of energy being sufficient to collapse and seal the voids (32) exposed at the cleaved end face (66), leaving a sealed cleaved end face (68). A lens may then be attached to the sealed cleaved end face (68), or the sealed cleaved end face (68) may be softened sufficiently to induce formation of a lensing surface such as a convex lensing surface (60) on the sealed end face (68).
