  • Methods for reconditioning glass manufacturing systems
    Patent number: 11130696
    Abstract: A method for reconditioning a glass manufacturing system includes establishing a reducing atmosphere in a glass melting vessel and draining a glass melt composition from the melting vessel while the reducing atmosphere is in the vessel. The pressure of the reducing atmosphere is greater than the pressure of the atmosphere surrounding the melting vessel and the reducing atmosphere is established by operating at least one combustion burner in the melting vessel in a fuel-rich condition.

  • Optical fibers having a varying clad index and methods of forming same
    Patent number: 11125937
    Abstract: 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.
