Abstract: A Photonic Crystal Fiber (PCF) a method of its production and a supercontinuum light source comprising such PCF. The PCF has a longitudinal axis and includes a core extending along the length of said longitudinal axis and a cladding region surrounding the core. At least the cladding region includes a plurality of microstructures in the form of inclusions extending along the longitudinal axis of the PCF in at least a microstructured length section. In at least a degradation resistant length section of the microstructured length section the PCF includes hydrogen and/or deuterium. In at least the degradation resistant length section the PCF further includes a main coating surrounding the cladding region, which main coating is hermetic for the hydrogen and/or deuterium at a temperature below Th, wherein Th is at least about 50° C., preferably 50° C.

Abstract: A method for producing ultra-thin glass sheets is provided that results in glass sheets with high edge strength. The method includes: hot forming a continuous glass ribbon with a glass thickness from molten glass; annealing the glass ribbon with an annealing rate chosen based on the glass thickness; producing a laser beam focus area that is longer than the glass thickness; introducing filamentary defects into the glass ribbon using the laser beam so that the filamentary defects extend from one face to the opposite face and are spaced apart from one another along the breaking lines to produce transverse breaking lines and longitudinal breaking lines with margins each comprising a thickened bead; separating the beads along the longitudinal breaking lines and separating glass sheets by severing along the transverse breaking lines.

Abstract: Systems and methods for texturing substrates (e.g., glass, metal, and the like) and the textured substrates produced using such systems and methods are disclosed. An exemplary system for texturing a substrate includes a first roller and a second roller. The first roller has a first textured surface. The first textured surface has a root mean square roughness between 40 to 1000 microns and an autocorrelation function greater than 0.5 for distances less than 50 microns.

Abstract: A method includes separately exposing selected portions of a first rigid substrate and a second rigid substrate to laser radiation, selectively etching the exposed portions of the first rigid substrate and the second rigid substrate using a chemical etchant and bonding the first rigid substrate to the second rigid substrate along a common interface to form a fluidic valve. The fluidic valve may be coupled to a fluidic haptics device, for example, which may be integrated into an artificial reality system.

Abstract: A method of manufacturing an optical fiber includes heating a distal end portion of an optical fiber preform made of glass; drawing a glass fiber from the distal end portion softened by the heating; and forming a coating layer made of resin on the glass fiber to form an optical fiber. The drawing includes periodically varying a tension that is applied to the glass fiber to vary a diameter of the glass fiber and a residual stress in an axial direction of the glass fiber so as to be in phases opposite to each other along the axial direction.

Abstract: A bent optical fiber has a glass optical fiber including a first end face, a second end face, a core, a stress applying portion, and a cladding, and a resin coating. An exposed region, from which a portion of the resin coating has been removed, includes a bent portion having a curvature of 0.1 (l/mm) or more. The stress distribution in the bent portion is such that the stress on the outermost peripheral portion of the cladding is 100 MPa or less, while the stress on the core is 30 MPa or more.

Abstract: A method for producing a multicore optical fiber includes: forming a common cladding tube by providing a first glass rod with a plurality of first holes and one or more second holes passing through the first glass rod in an axial direction, the one or more second holes having a diameter different from a diameter of the plurality of first holes; subjecting inner surfaces of the plurality of first holes and inner surfaces of the one or more second holes to a gas-phase process; and inserting a plurality of core rods into the plurality of first holes subjected to the gas-phase process, respectively, inserting a refractive index changing part rod into each of the one or more second holes subjected to the gas-phase process, and performing thermal integration to form a second glass rod. The common cladding tube is formed such that the diameter of the plurality of first holes is no more than 4 times the diameter of the one or more second holes.

Abstract: A transfer device and use thereof, and a glass bending forming system are provided. The transfer device includes a suction table. The suction table has a first edge-region and a second edge-region. The first edge-region surrounds the second edge-region. The suction table defines a first suction groove, multiple first suction holes, a first suction channel, and a second suction channel. The first suction groove is defined in the first edge-region. The multiple first suction holes are defined in the second edge-region. The first suction channel is in communication with the first suction groove and is used for providing a first negative pressure. The second suction channel is in communication with the multiple first suction holes and is used for providing a second negative pressure. The first negative pressure and the second negative pressure are used for sucking at least one glass sheet on the transfer device.
