    Abstract: Assemblies, optical connectors, and methods for forming fiber arrays using laser bonded optical fibers are disclosed. In one embodiment, a method of forming a fiber array includes placing an optical fiber on a surface of a substrate, directing a laser beam into the optical fiber disposed on the surface of the substrate, melting, using the laser beam, a material of the substrate to create a first laser bond zone between the optical fiber and the surface of the substrate, applying an adhesive to the optical fiber and the substrate to create an adhesive bond zone between the optical fiber and the surface of the substrate, and cutting the optical fiber and the substrate to create a first section of the fiber array and a second section of the fiber array. The first section of the fiber array includes a first portion of the optical fiber, a first portion of the substrate, a first portion of the adhesive bond zone, and the first laser bond zone, and the second section of the fiber array includes a second portion of the optical fiber, a second portion of the substrate, and a second portion of the adhesive bond zone.

    Abstract: A light-diffusing optical fiber with a light-guiding core having a plurality of elongated glass rods each oriented substantially parallel with each other and with the length of the optical fiber. The fiber also includes a cladding surrounding the glass core, the cladding having a refractive index similar to, or lower than, a refractive index of the glass core. The light-guiding core includes a plurality of gaps formed between the plurality of elongated glass rods, the plurality of gaps scattering light away from the light-guiding core and through the cladding.

    Abstract: Glasses with compressive stress profiles that allow higher surface compression and deeper depth of layer (DOL) than is allowable in glasses with stress profiles that follow the complementary error function at a given level of stored tension. In some instances, a buried layer or local maximum of increased compression, which can alter the direction of cracking systems, is present within the depth of layer. Theses compressive stress profiles are achieved by a three step process that includes a first ion exchange step to create compressive stress and depth of layer that follows the complimentary error function, a heat treatment at a temperature below the strain point of the glass to partially relax the stresses in the glass and diffuse larger alkali ions to a greater depth, and a re-ion-exchange at short times to re-establish high compressive stress at the surface.
