Patent number: 11878932Abstract: A method of melting glass and glass-ceramics that includes the steps: conveying a batch of raw materials into a submerged combustion melting apparatus, the melting apparatus having liquid-cooled walls and a floor; directing a flame into the batch of raw materials and the melted batch with sufficient energy to form the raw materials into the melted batch; and heating a delivery orifice assembly in the floor of the submerged melting apparatus to convey the melted batch through the orifice assembly into a containment vessel. The melted batch has a glass or glass-ceramic composition that is substantially reactive to a refractory material comprising one or more of silica, zirconia, alumina, platinum and platinum alloys.Type: GrantFiled: May 23, 2022Date of Patent: January 23, 2024Assignee: CORNING INCORPORATEDInventors: Curtis Richard Cowles, Gilbert De Angelis, Nicolas LeBlond, David John McEnroe, Jeffrey Lee Merriman, Rand Alan Murnane, Katherine Rose Rossington, Michael Joshua Snyder

Patent number: 10921512Abstract: Methods of manufacturing multi-mode optical fiber, and multi-mode optical fiber produced thereby, are disclosed. According to embodiments, a method for forming an optical fiber may include heating a multi-mode optical fiber preform and applying a draw tension to a root of the multi-mode optical fiber preform on a long axis of the multi-mode optical fiber preform thereby drawing a multi-mode optical fiber from the root of the multi-mode optical fiber preform. The draw tension may be modulated while the multi-mode optical fiber is drawn from the root of the multi-mode optical fiber preform. Modulating the draw tension introduces stress perturbations in the multi-mode optical fiber and corresponding refractive index perturbations in a core of the multi-mode optical fiber.Type: GrantFiled: September 25, 2018Date of Patent: February 16, 2021Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Curtis Richard Cowles, Richard Michael Fiacco, Ming-Jun Li, Jason Roy Pace, Jeffery Scott Stone
