Patent number: 9919946Abstract: A method for forming an optical fiber preform and fibers drawn from the preform. The method includes forming a soot cladding monolith, inserting a consolidated core cane into the internal cavity, and processing the resulting core-cladding assembly to form a preform. Processing may include exposing the core-cladding assembly to a drying agent and/or dopant precursor, and sintering the core-cladding assembly in the presence of a reducing agent to densify the soot cladding monolith onto the core cane to form a preform. The preform features low hydroxyl content and low sensitivity to hydrogen. Fibers drawn from the preform exhibit low attenuation losses from absorption by the broad band centered near 1380 nm.Type: GrantFiled: January 23, 2017Date of Patent: March 20, 2018Assignee: Corning IncorporatedInventors: Amanda Lee Billings, Dana Craig Bookbinder, Robert Brett Desorcie, Liam Ruan de Paor, Pushkar Tandon, Li Yang

Patent number: 9878943Abstract: The present disclosure is directed to a method of making an optical fiber with improved bend performance, the optical fiber having a core and at least one cladding layer, and a chlorine content in the in the last layer of the at least one cladding layer that is greater than 500 ppm by weight. The fiber is prepared using a mixture of a carrier gas, a gaseous chlorine source material and a gaseous reducing agent during the sintering of the last or outermost layer of the at least one cladding layer. The inclusion of the reducing gas into a mixture of the carrier gas and gaseous chlorine material reduces oxygen-rich defects that results in at least a 20% reduction in TTP during hydrogen aging testing.Type: GrantFiled: March 28, 2017Date of Patent: January 30, 2018Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Robert Brett Desorcie, Hazel Benton Matthews, III, Pushkar Tandon

Patent number: 8925354Abstract: Methods of forming an overclad portion of an optical fiber are described which include positioning a core cane member in an overclad tube to form a rod and tube assembly. Thereafter, glass soot pellets are positioned in the rod and tube assembly between the core cane member and an interior sidewall of the overclad tube. The rod and tube assembly is then redrawn under conditions effective to form the overclad tube and the glass soot pellets into a continuous, void-free glass layer surrounding the core cane member at a sintering time tsinter of at least 1800 seconds thereby forming an overclad portion of an optical fiber.Type: GrantFiled: November 4, 2009Date of Patent: January 6, 2015Assignee: Corning IncorporatedInventors: Robert Brett Desorcie, Peter Joseph Ronco, Roger A.

Patent number: 8869566Abstract: A method and apparatus for making an optical fiber preform. The apparatus has an outer wall and an inner wall. The outer wall surrounds the inner wall and the inner wall surrounds an inner cavity of the apparatus. A core rod is deposited in the inner cavity after which particulate glass material, such as glass soot, is deposited in the inner cavity around the core rod. The core rod has at least 10 percent of the final cladding soot already applied thereto. A radially inward pressure is applied against the particulate glass material to pressurize the particulate glass material against the core rod.Type: GrantFiled: August 25, 2011Date of Patent: October 28, 2014Assignee: Corning IncorporatedInventors: Martin Wade Allen, Steven Bruce Dawes, Robert Brett Desorcie, Nicolas LeBlond, Roger A Rose, Pushkar Tandon, Kochuparambil Vargheese, Li Yang

Publication number: 20140174133Abstract: Methods for forming optical fiber preforms are disclosed. According to one embodiment, a method for forming an optical fiber preform includes forming a preform core portion from silica-based glass soot. The silica-based glass soot may include at least one dopant species for altering an index of refraction of the preform core portion. A selective diffusion layer of silica-based glass soot may be formed around the preform core portion to form a soot preform. The selective diffusion layer may have an as-formed density greater than the density of the preform core portion. A diffusing species may be diffused through the selective diffusion layer into the preform core portion. The soot preform may be sintered such that the selective diffusion layer has a barrier density which is greater than the as-formed density and the selective diffusion layer prevents diffusion of the at least one dopant species through the selective diffusion layer.Type: ApplicationFiled: December 16, 2013Publication date: June 26, 2014Applicant: Corning IncorporatedInventors: Amanda Lee Billings, Liam Ruan de Paor, Robert Brett Desorcie, Robert Arnold Knowlton, Pushkar Tandon

Patent number: 8464556Abstract: Method of making a microstructured optical fiber. Silica glass based soot is deposited on a substrate to form at least a portion of an optical fiber preform by traversing a soot deposition burner with respect to said substrate at a burner traverse rate greater than 3 cm/sec, thereby depositing a layer of soot having a thickness less than 20 microns for each of a plurality of burner passes. At least a portion of the soot preform is then consolidated inside a furnace to remove greater than 50 percent of the air trapped in said soot preform, said consolidating taking place in a gaseous atmosphere containing krypton, nitrogen, or mixtures thereof under conditions which are effective to trap a portion of said gaseous atmosphere in said preform during said consolidation step, thereby forming a consolidated preform which when viewed in cross section will exhibit at least 50 voids therein.Type: GrantFiled: May 5, 2008Date of Patent: June 18, 2013Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Robert Brett Desorcie, Mark Alan McDermott, Pushkar Tandon
