Patent number: 11774676Abstract: The present disclosure relates to a process by which an optical fiber array or a single optical fiber is cleaved with a laser-cleaving apparatus. The coating material is stripped or removed from a section of an optical fiber array or single optical fiber; a coated or ribbonized section of the optical fiber array or the single optical fiber is secured in a holder; the holder is aligned inside the laser-cleaving apparatus; the laser cleaves the stripped ends of the fibers in the optical fiber array or the single optical fiber; the laser-cleaved ends of the optical fiber(s) are then mechanically separated to remove the free ends from the optical fibers in the optical fiber array or the single optical fiber, leaving a cleaved array of optical fibers or a single cleaved optical fiber. The cleaving process enables the optical fiber array or single optical fiber to be cleaved at flexible locations along an optical fiber ribbon, optical fiber, or optical fiber apparatus (e.g.Type: GrantFiled: August 7, 2021Date of Patent: October 3, 2023Assignee: Corning Research & Development CorporationInventors: Scott Robertson Bickham, Joel Patrick Carberry, Randy LaRue McClure, Craig John Mancusi Ungaro, Qi Wu, Lei Yuan

Publication number: 20230236356Abstract: The present disclosure relates to a thin coated optical fiber that enables connector assembly without stripping the optical fiber. In particular, the thin coating comprises a hard coating, a dye concentrate, and an adhesion promoter. The formulation of the coating promotes adhesion to a glass cladding of the optical fiber and to a ferrule bore (into which the optical fiber is inserted) by not causing silane decomposition of the coating. Moreover, the coating is colored to enable, among other things, fiber identification within a connector. The thin coated optical fibers exhibit good mechanical and optical performance properties as discussed herein.Type: ApplicationFiled: January 3, 2023Publication date: July 27, 2023Inventors: Jeffrey Scott Clark, Matthew Ryan Drake, Yunfeng Gu, Ming-Jun Li, Joseph Edward McCarthy, Randy LaRue McClure, Weijun Niu, Qi Wu

Publication number: 20230038299Abstract: Methods and systems for removing coatings from optical fibers. A system includes a gas source for providing gas, and a heater configured to heat the gas. The system further includes a holder comprising first and second attachment features, wherein the attachment features secure a coated optical fiber along a removal path. The system further includes at least one nozzle connected to the gas source, wherein the at least on nozzle is aimed in a nozzle direction that is towards the removal path at a pitch, such that the nozzle is non-perpendicular towards the removal path. The nozzle further directs a continuous stream of the heated gas towards the coated optical fiber causing the coating of the coated optical fiber to be removed. The methods and systems may employ a second nozzle that may be offset from the first nozzle angularly and/or laterally with respect to the removal path.Type: ApplicationFiled: August 9, 2022Publication date: February 9, 2023Inventors: Scott Robertson Bickham, Randy LaRue McClure, William James Miller, Christopher Allen Page, Qi Wu

Publication number: 20080204741Abstract: Disclosed is a method for the detection and quantification of defects in transparent substrates and, more particularly, in glass sheets. The method comprises providing a transparent planar substrate having a top surface and a bottom surface. The surface topography of at least a portion of the top surface of the provide transparent planar substrate is measured to obtain a three dimensional top surface profile having a sub-nanometer level of precision. From the three dimensional surface profile measurement, the existence of one or more surface variations in the three dimensional surface profile having an amplitude greater than a predetermined tolerance can be identified and/or quantified.Type: ApplicationFiled: February 22, 2008Publication date: August 28, 2008Inventors: Keith Mitchell Hill, Randy LaRue McClure, Richard Sean Priestley
