摘要： A multimode optical fiber includes a core portion (102) formed from SiO 2 intentionally doped with a single dopant, wherein the single dopant is phosphorous or a compound of phosphorous. A glass cladding portion (103) surrounds and is in direct contact with the core portion (102). The glass cladding portion comprises an outer cladding portion (108) and a low-index moat (106) disposed between the core portion (102) and the outer cladding portion (108). The optical fiber may also have a bandwidth greater than or equal to 2000 MHz-km for each wavelength within a wavelength operating window centered on a wavelength within an operating wavelength range from about 850 nm to about 1310 nm, the wavelength operating window having a width greater than 100 nm. The optical fiber may also have a restricted launch bend loss less than or equal to 0.5 dB/(2 turns around a 15 mm diameter mandrel) at 850 nm.

摘要： 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.

摘要： 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.

摘要： 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.
