Publication number: 20180319695Abstract: According to one embodiment, a method of forming a laminated glass ribbon may include flowing a molten glass core composition and a molten glass cladding composition in a vertically downward direction. The molten glass core composition may be contacted with the molten glass cladding composition to form the laminated glass ribbon comprising a glass core layer formed from the molten glass core composition and a glass cladding layer formed from the molten glass cladding composition. Core beads located proximate an edge of the glass core layer and clad beads located proximate an edge of the glass cladding layer may be compressed while the glass core layer and the glass cladding layers have viscosities greater than or equal to the viscosity at their softening points as the laminated glass ribbon is drawn in the vertically downward direction.Type: ApplicationFiled: November 3, 2016Publication date: November 8, 2018Inventors: Alexey Sergeyevich Amosov, James Gary Anderson, Kaushik Arumbuliyur Comandur, Frank Coppola, Hung Cheng Lu, Anca Daniela Miller, Ibraheem Rasool Muhammad, Jon Anthony Passmore, Michael Clement Ruotolo, Jr., Zheming Zheng

Patent number: 9250386Abstract: Disclosed is an optical fiber having a core with an alkali metal oxide dopant in an peak amount greater than about 0.002 wt. % and less than about 0.1 wt. %. The alkali metal oxide concentration varies with a radius of the optical fiber. By appropriately selecting the concentration of alkali metal oxide dopant in the core and the cladding, a low loss optical fiber may be obtained. Also disclosed are several methods of making the optical fiber including the steps of forming an alkali metal oxide-doped rod, and adding additional glass to form a draw perform. Preferably, the draw preform has a final outer dimension (d2), wherein an outer dimension (d1) of the rod is less than or equal to 0.06 times the final outer dimension (d2). In a preferred embodiment, the alkali metal oxide-doped rod is inserted into the centerline hole of a preform to form an assembly.Type: GrantFiled: June 25, 2014Date of Patent: February 2, 2016Assignee: Corning IncorporatedInventors: James Gary Anderson, Dana Craig Bookbinder, Lisa Carine Chacon, Calvin Thomas Coffey, Adam James Ellison, Gregory Gerard Gausman, Rostislav Radiyevich Khrapko, Stephan Lvovich Logunov, Michael Thomas Murtagh, Clinton Damon Osterhout, Sabyasachi Sen, William Anthony Whedon
