Abstract: A system and method for making an edge section of a thin, high purity fused silica glass sheet. The method includes a step of directing a laser to melt through the glass sheet with localized heating of a narrow portion of the glass sheet to form an edge section of the glass sheet, and continuing the edge section to form a closed loop defining a perimeter of the glass sheet. The method further includes rapidly cooling the glass sheet through the glass transition temperature as the melted glass of the edge section contracts and/or solidifies to form an unrefined-bullnose shape extending between first and second major surfaces of the glass sheet.

Abstract: A multicore fiber is provided. The multicore fiber includes a plurality of cores spaced apart from one another, and a cladding surrounding the plurality of cores and defining a substantially rectangular or cross-sectional shape having four corners. Each corner has a radius of curvature of less than 1000 microns. The multicore fiber may be drawn from a preform in a circular draw furnace in which a ratio of a maximum cross-sectional dimension of the preform to an inside diameter of the preform to an inside diameter of the draw furnace is greater than 0.60. The multicore fiber may have maxima reference surface.

Abstract: Methods of forming a glass tube are described. In one embodiment, the method includes heating a glass boule to a temperature above a glass transition temperature of the glass boule, drawing the glass tube from the glass boule in a vertically downward direction, and flowing a pressurized gas through a channel of the glass boule as the glass tube is drawn. The glass boule includes an outer surface defining an outer diameter of the glass boule and a channel extending through the glass boule defining an inner diameter of the glass boule. Drawing the glass tube decreases the outer diameter of the glass boule to an outer diameter of the glass tube and flowing the pressurized gas through the channel increases the inner diameter of the glass boule to an inner diameter of the glass tube. Glass boules, glass tubes, and apparatuses for making the same are also described.

Abstract: A method of making an LED device and an LED device using a high-silica, fully-sintered glass substrate is provided. The high-silica substrate is at least 99% silica and is thin, such as less than 200 μm in thickness. A phosphor containing layer is deposited on to the substrate and is laser sintered on the substrate such that a portion of the sintered phosphor layer embeds in the material of the substrate.

Abstract: A porous soot sheet is formed using a roll-to-roll glass soot deposition and sintering process. The soot sheet formation involves depositing glass soot particles on a deposition surface to form a supported soot layer, removing the soot layer from the deposition surface to form a soot sheet, and heating a portion of the soot sheet to locally-sinter the glass soot particles and form a porous soot part having a sintered peripheral edge.

Abstract: A spray coating apparatus that applies a coating material onto outer surfaces of glass objects includes a coating material source that includes a coating material. A spray nozzle assembly includes a spray nozzle fluidly connected to the coating material source. The spray nozzle is arranged and configured to direct the coating material in a first direction toward the glass object and provide an overspray amount of the coating material by the glass object such that the overspray amount bypasses a non-line of sight area of the glass object. A turn nozzle assembly includes a turn nozzle fluidly connected to a pressurized gas source. The turn nozzle is arranged and configured to direct pressurized gas in a second direction different than the first direction toward the non-line of sight area of the glass package to redirect the coating material onto the non-line of sight area.
