Patent number: 11247939Abstract: A glass article having a glass bump formed integrally thereon by laser-irradiation methods. The glass bump includes a lower region connected to an upper region by an inflection region. The lower region projects from a surface of the glass article and is defined by concavely rounded sides with a radius of curvature R1. The upper region includes a transition portion and a top portion. The transition portion is defined by convexly rounded sides with a radius of curvature R2. The transition portion connects to the lower portion via the inflection region. The upper portion connects to the transition portion and is defined by a convexly rounded top surface with a radius of curvature R3, which is greater than radius of curvature R2.Type: GrantFiled: July 30, 2019Date of Patent: February 15, 2022Assignee: Corning IncorporatedInventors: Leonard Thomas Masters, Alexander Mikhailovich Streltsov

Patent number: 11247932Abstract: The liquid-assisted micromachining methods include methods of processing a substrate made of a transparent dielectric material. A working surface of the substrate is placed in contact with a liquid-assist medium that comprises fluorine. A focused pulsed laser beam is directed through a first substrate surface and through the opposite working surface to form a focus spot in the liquid-assist medium. The focus spot is then moved over a motion path from its initial position in the liquid-assist medium through the substrate body in the general direction from the working surface to the first surface to create a modification of the transparent dielectric material that defines in the body a core portion. The core portion is removed to form the substrate feature, which can be a through or closed fiber hole that supports one or more optical fibers. Optical components formed using the processed substrate are also disclosed.Type: GrantFiled: January 25, 2019Date of Patent: February 15, 2022Assignee: Corning IncorporatedInventors: Jeffery Alan DeMeritt, Davide Domenico Fortusini, Andrey Kobyakov, David Mark Lance, Leonard Thomas Masters, Ulrich Wilhelm Heinz Neukirch, Alexander Mikhailovich Streltsov, James Scott Sutherland
