Disclosed is a method of forming a glass article. In the method, a mid-frame is adhered to a glass sheet in a flat configuration. The glass sheet has a first major surface and a second major surface opposite to the first major surface. The mid-frame is adhered to the second major surface of the glass sheet. The glass sheet and mid-frame are bent over a forming surface of a chuck so that the glass sheet is in a curved configuration. The forming surface includes a first radius of curvature of 20 mm or more, and the first major surface of the glass sheet conforms to the forming surface. A frame is attached to the mid-frame, and the frame holds the glass sheet in the curved configuration.

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.
