Patent number: 11198635Abstract: Preparation of halogen-doped silica is described. The preparation includes doping silica with high halogen concentration and sintering halogen-doped silica to a closed-pore state in a gas-phase environment that has a low partial pressure of impermeable gases. Impermeable gases are difficult to remove from halogen-doped fiber preforms and lead to defects in optical fibers drawn from the preforms. A low partial pressure of impermeable gases in the sintering environment leads to a low concentration of impermeable gases and a low density of gas-phase voids in densified halogen-doped silica. Preforms with fewer defects result.Type: GrantFiled: August 1, 2019Date of Patent: December 14, 2021Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Steven Bruce Dawes, Richard Michael Fiacco, Brian Lee Harper, Pushkar Tandon

Patent number: 11125937Abstract: An optical fiber with low attenuation and methods of making same are disclosed. The optical fiber has a core, an inner cladding surround the core, and an outer cladding surrounding the inner cladding. The outer cladding is chlorine-doped such that the relative refractive index varies as a function of radius. The radially varying relative refractive index profile of the outer cladding reduces excess stress in the core and inner cladding, which helps lower fiber attenuation while also reducing macrobend and microbend loss. A process of fabricating the optical fiber includes doping an overclad soot layer of a soot preform with chlorine and then removing a portion of the chlorine dopant from an outermost region of the overclad soot layer. The soot preform with the modified chlorine dopant profile is then sintered to form a glass preform, which can then be used for drawing the optical fiber.Type: GrantFiled: September 7, 2018Date of Patent: September 21, 2021Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Paul Andrew Chludzinski, Brian Lee Harper, Ming-Jun Li, Snigdharaj Kumar Mishra, Sonya Marie Raney, Pushkar Tandon

Patent number: 10947149Abstract: Preparation of halogen-doped silica is described. The preparation includes doping silica with high halogen concentration and sintering halogen-doped silica to a closed-pore state. The sintering includes a high pressure sintering treatment and a low pressure sintering treatment. The high pressure sintering treatment is conducted in the presence of a high partial pressure of a gas-phase halogen doping precursor and densifies a silica soot body to a partially consolidated state. The low pressure sintering treatment is conducted in the presence of a low partial pressure of gas-phase halogen doping precursor and transforms a partially consolidated silica body to a closed-pore state. The product halogen-doped silica glass exhibits little foaming when heated to form fibers in a draw process or core canes in a redraw process.Type: GrantFiled: October 23, 2018Date of Patent: March 16, 2021Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Steven Bruce Dawes, Richard Michael Fiacco, Brian Lee Harper, Ming-Jun Li, Pushkar Tandon
