A method for generating various stress profiles for chemically strengthened glass. An alkali aluminosilicate glass is brought into contact with an ion exchange media such as, for example, a molten salt bath containing an alkali metal cation that is larger than an alkali metal cation in the glass. The ion exchange is carried out at temperatures greater than about 420&#xb0; C. and at least about 30&#xb0; C. below the anneal point of the glass.

A multicore optical fiber includes two or more cores, a common interior cladding surrounding the two or more cores, and a common exterior cladding surrounding the common interior cladding. The common exterior cladding has a lower relative refractive index than the common interior cladding and reduces tunneling losses from the cores. The reduced tunneling loss allows placement of cores closer to the edge of the fiber, thus providing multicore optical fibers having higher core count for a given fiber diameter. Separation between cores is controlled to minimize crosstalk.

Multicore fiber with exterior cladding region

An apparatus for downwardly drawing a glass ribbon includes a forming vessel including an upper portion including a pair of outside surfaces and a forming wedge portion including a pair of downwardly inclined forming surfaces converging along a downstream direction to form a bottom edge.

Dual-elevation edge roll system for fused downdraw glass forming

Disclosed herein are apparatuses and methods for drawing sheet glass. More particularly, one or more sets of edge rolls can be configured to have a rotation axis angled away from a line orthogonal to the direction of flow of a ribbon of glass and positioned so as to contact the glass in the viscous region of the draw. Through control over the orientation and position of the one or more sets of edge rolls, sheet width attenuation may be eliminated, thickness of the beads that form along the edges of the glass sheet may be reduced, and instabilities associated with sheet width variation may be eliminated.

Systems and methods utilizing two Airy beams to process a non-rounded edge of a glass substrate or to cleave a glass substrate are disclosed. The method includes generating first and second Airy beams and causing them to cross at a crossing to define a curved intensity profile in the vicinity of the crossing point where the first and second Airy beams have respective local radii of curvature RA and RB. The method also includes scanning the curved intensity profile either along the non-rounded outer edge or through the glass along a scan path to form on the glass substrate a rounded outer edge having a radius of curvature RE that is smaller than the first and second local radii of curvature RA and RB. The radius of curvature RE can be adjusted by changing a beam angle between the first and second Airy beams.
