Patent number: 11249249Abstract: A method is used to select a multimode fiber meeting requirements of a first minimum bandwidth at a first wavelength and a second minimum bandwidth at a second wavelength different from the first wavelength. Differential mode delay (DMD) data is measured for the multimode fiber at the first wavelength. The DMD data comprises output laser pulse data as a function of the radial position of an input laser pulse having the first wavelength. The DMD data is transformed into mode group space, to obtain relative mode group delay data as a function of mode group. The multimode fiber is selected based on meeting requirements of the first minimum bandwidth at the first wavelength based on a first set of criteria, comprising a first criterion using as input the measured differential mode delay (DMD) data for the multimode fiber measured at the first wavelength.Type: GrantFiled: June 3, 2019Date of Patent: February 15, 2022Assignee: Corning IncorporatedInventors: John Steele Abbott, III, Scott Robertson Bickham, Thomas Arthur Hanson, Tiffany Ann Lindstrom

Publication number: 20190276356Abstract: Strengthened glass substrates and methods of reducing warp in strengthened glass substrates having 3D and 2.5D shapes are disclosed. In one embodiment, a strengthened glass-based article includes a first surface, a second surface opposite the first surface, and an edge between the first surface and the second surface. The edge is asymmetric with respect to a plane that is located at an average depth of the strengthened glass-based article and is parallel to the first surface and the second surface. The strengthened glass-based article has an expected warp WE based at least in part on a shape of the asymmetric edge of the strengthened glass-based article. An actual warp WA of the strengthened glass-based article is less than 85% of the expected warp metric WE of the strengthened glass-based article. The actual warp WA of the strengthened glass-based article is measured with a concave surface facing up.Type: ApplicationFiled: November 29, 2017Publication date: September 12, 2019Inventors: John Steele Abbott, Douglas Clippinger Allan, John Martin Darfin, Sumalee Likitvanichkul Fagan, David Lee Weidman, David Inscho Wilcox -

Patent number: 9031813Abstract: Methods and apparatus (100,200) for estimating the gravity-free shape of a flexible object (140) such as a thin sheet of glass are provided. In certain embodiments, an estimate of the gravity-free shape is produced using a bed-of-nails (BON) gauge (100) and then the shape is measured at a higher spatial resolution using a second gauge (200), with the theoretical sag between the pins (110) of the BON gauge being subtracted from the shape measured by the second gauge. In other embodiments, shape measurements are performed on both sides of the object (140) and used to estimate the reliability of the gravity-free shape estimate. In further embodiments, the bed-of-nails gauge (100) uses a least squares minimization procedure in adjusting the heights of the pins (110).Type: GrantFiled: August 27, 2010Date of Patent: May 12, 2015Assignee: Corning IncorporatedInventors: John Steele Abbott, III, Daniel R Harvey, Correy Robert Ustanik
