  • Patent number: 10079189
    Abstract: Disclosed herein is the formation of p-type transparent conducting oxides (TCO) having a structure of MgxNi1-xO or ZnxNi1-xO. These structures disrupt the two-dimensional confinement of individual holes (the dominant charge carrier transport mechanism in pure NiO) creating three-dimensional hole transport by providing pathways for hole transfer in directions that are unfavorable in pure NiO. Forming these structures preserves NiO's transparency to visible light since the band gaps do not deviate significantly from that of pure NiO. Furthermore, forming MgxNi1-xO or ZnxNi1-xO does not lead to hole trapping on O ions adjacent to Zn and Mg ions. The formation of these alloys will lead to creation of three-dimensional hole transport and improve NiO's conductivity for use as p-type TCO, without adversely affecting the favorable properties of pure NiO.

  • Patent number: 9164251
    Abstract: A communication line such as an optical fiber or cable is attached along a wall, ceiling, trim piece, or other selected surface on or inside of a building, by paying out the fiber from an applicator tool while the tool guides the fiber along the selected surface. The outer surface of the fiber is prepared so that the fiber will be in a temporarily tacky condition when the fiber is pressed onto the selected surface by the applicator tool. The fiber is pre-coated with an adhesive that is activated by a fluid supplied by the applicator tool. As the applicator tool presses the fiber onto the selected surface, the activated adhesive coating on the fiber quickly becomes non-tacky to attach the fiber firmly to the surface.

  • Patent number: 9146361
    Abstract: Cables having non-stripping, or buffer-free, optical fibers are disclosed. The cables each have a buffer-free optical fiber including a core, cladding layer and a thin protective coating enclosing the cladding and having an overall diameter of 125 ?m. This protective coating protects the cladding and core from moisture and provides structural integrity to prevent physical damage to the fiber during installation and termination with connectors. Embodiments of this non-stripping fiber do not require removal of a buffer layer during field termination so connections can be formed using simple cleaving techniques. As such, the field termination process for embodiments is simplified compared with conventional approaches.

  • Patent number: 9031099
    Abstract: An optical active fiber is configured with an asymmetrically-shaped core having at least one long axis and a shortest axis which extends transversely to the long axis. The outmost cladding of the active fiber is configured with a marking indicating the orientation of the short axis. The marking allows for bending the fiber so that the shortest axis extends along and lies in the plane of the bend thereby minimizing distortion of a mode which is guided by the asymmetrically-shaped core as light propagates along the bend.
