    Abstract: Embodiments of this disclosure include a cold-formed cover glass substrate comprising a first end, a second end opposing the first end, opposing first and second major surfaces, a width, a length; a first axis and a second axis both extending along the width or both extending along the length; a first portion extending from the first axis to the first end that comprises a first radius of curvature, and a second portion extending from the first axis to the second axis. In one or more embodiments, the second portion includes a second radius of curvature that increases or decreases from the first axis to the second axis. In one or more embodiments, the cold-formed cover glass substrate comprises a third portion extending from the second axis to the second end, wherein the third portion differs from the first portion.

    Abstract: A multimode optical fiber, and a method of making the fiber, are provided according to the following steps and elements: forming a core preform with a graded refractive index that includes silica and an up-dopant; drawing the core preform into a core cane; forming an inner annular segment preform that includes silica soot and an up-dopant surrounding the core cane; and forming a depressed-index annular segment preform that includes silica soot surrounding the inner annular segment preform. The method also includes the steps: forming an outer annular segment preform that includes silica soot and an up-dopant surrounding the depressed-index annular segment preform; doping the inner, depressed-index and outer annular segment preforms simultaneously or nearly simultaneously with a down-dopant; and consolidating the segment preforms simultaneously or nearly simultaneously into inner, depressed-index and outer annular segments.

    Abstract: Disclosed is a method of forming a glass article in which a glass sheet is bent over a forming surface of a chuck. The forming surface defines a first shape including a curvature having a radius of curvature of 1000 mm or less, and the glass sheet includes a first major surface in contact with the forming surface. A frame is adhered to a second major surface of the glass sheet. The frame includes a frame support surface defining a second shape including a second curvature having a second radius of curvature of 1000 mm or less. A total force is applied to the glass sheet so that the glass sheet forms a third shape including a third curvature having a third radius of curvature of 1000 mm or less. The third shape deviates from the second shape by 2 mm or less across the frame support surface.
