Patent number: 10442721Abstract: In a unit gravity environment, a glass preform is encased in a material to generate an encased glass preform. The material remains solid at the glass preform's crystal melting temperature and is inert with respect to the glass preform. The encased glass preform is placed in a microgravity environment and heated to a temperature above the crystal melting temperature until the glass preform melts and is free of crystals, wherein a crystallite-free glass preform is encased within the material. The crystallite-free glass preform is then cooled in the microgravity environment to generate a solid crystallite-free glass preform encased within the material. While still in the microgravity environment, the material encasing the solid crystallite-free glass preform is removed in the microgravity environment and the solid crystallite-free glass preform is polished. A glass optical fiber is then drawn from the solid crystallite-free glass preform in the microgravity environment.Type: GrantFiled: April 15, 2019Date of Patent: October 15, 2019Inventors: Dennis S. Tucker, Jeremy A. Tucker

Patent number: 10442719Abstract: Processes of chamfering and/or beveling an edge of a glass or other substrate of arbitrary shape using lasers are described herein. Three general methods to produce chamfers on glass substrates are disclosed. The first method involves cutting the edge with the desired chamfer shape utilizing an ultra-short pulse laser. Treatment with the ultra-short laser may be optionally followed by a CO2 laser for fully automated separation. The second method is based on thermal stress peeling of a sharp edge corner, and it has been demonstrated to work with different combination of an ultrashort pulse and/or CO2 lasers. A third method relies on stresses induced by ion exchange to effect separation of material along a fault line produced by an ultra-short laser to form a chamfered edge of desired shape.Type: GrantFiled: October 31, 2014Date of Patent: October 15, 2019Assignee: Corning IncorporatedInventors: Sasha Marjanovic, Albert Roth Nieber, Garrett Andrew Piech, Helmut Schillinger, Sergio Tsuda, Robert Stephen Wagner
