摘要： A method of manufacturing a tuned optical fiber includes providing a first preform from a set of like preforms each having substantially the same refractive index profile, including amount of axial variation relative to a target refractive index profile. The method includes drawing a reference optical fiber from the first preform and measuring a variation in an optical or physical property as a function of axial position. The method also includes drawing from a second preform from the set of like preforms the tuned optical fiber. The drawing includes using a time-varying tension that reduces the amount of variation of the optical or physical property of interest. The time-varying tension is defined by an amount of axial stress imparted to the tuned fiber needed to alter the refractive index profile and the at least one optical or physical property based on a stress-optic effect.

摘要： An article includes an optical transforming layer and a guide region positioned inside and adjacent to at least a portion of a perimeter of the optical transforming layer. The guide region comprises an inlet end positioned adjacent to a first surface of the optical transforming layer and an outlet end positioned adjacent a second surface of the optical transforming layer. The guide region propagates light from the inlet end to the outlet end such that the light is directed from the first surface to the second surface. The guide region includes a phase-separated glass comprising a continuous network phase and a discontinuous phase. A relative difference in index of refraction between the continuous network phase and the discontinuous phase is greater than or equal to 0.3%. The discontinuous phase comprises elongated shaped regions aligned along a common axis and having an aspect ratio greater than or equal to 10:1.

摘要： A method of manufacturing a strengthened glass article includes forming a glass-to-glass laminate by fusing clad and core glasses, where the clad has greater high-temperature coefficient of thermal expansion (HTCTE) than the core but a lesser low-temperature coefficient of thermal expansion (LTCTE). The method includes cooling the laminate to impart stresses through contraction mismatch between the clad and core, where stresses in the laminate from HTCTE differences at least partially offset stresses in the laminate from LTCTE. After the cooling, the method includes modifying geometry of the laminate, then relaxing at least some of the stresses in the glass-to-glass laminate from differences in the HTCTE.

摘要： Methods of manufacturing a glass ribbon include moving a ribbon of glass-forming material along a travel path in a travel direction. Methods include sensing a thickness of the ribbon of glass-forming material at a plurality of locations of the ribbon of glass-forming material. Methods include identifying a location of the plurality of locations in which a corresponding thickness at the location exceeds a target thickness. Methods include correlating a rate of thickness change and a thickness difference between the corresponding thickness and the target thickness to a laser power. Methods include directing a laser beam at the laser power toward the ribbon of glass-forming material to decrease a viscosity at the location and attain the target thickness at the location.

摘要： Durable and scratch resistant articles including an optical coating with a gradient. An article comprises: a substrate; and an optical coating having a thickness and a first gradient portion. A refractive index of the optical coating varies along a thickness of the optical coating.

The absolute value of the slope of the refractive index of the first gradient portion is 0.1/nm or less everywhere along the thickness of the first gradient portion. The article exhibits an average single-surface reflectance of 15% to 98% over the wavelength range 400 nm-700 nm. The article also exhibits a maximum hardness in the range from about 10 GPa to about 30 GPa.
