  • Publication number: 20200241213
    Abstract: A method of cleaving an optical fiber comprises inserting the optical fiber through a bore of a holding member, securing the optical fiber to the holding member with a bonding agent, operating at least one laser to emit at least one laser beam, and directing the at least one laser beam from the at least one laser to the end face of the holding member. At least a portion of the at least one laser beam reflects off the end face of the holding member and is thereafter incident on an end portion of the optical fiber.

  • Patent number: 10494290
    Abstract: Systems and methods utilizing two Airy beams to process a non-rounded edge of a glass substrate or to cleave a glass substrate are disclosed. The method includes generating first and second Airy beams and causing them to cross at a crossing to define a curved intensity profile in the vicinity of the crossing point where the first and second Airy beams have respective local radii of curvature RA and RB. The method also includes scanning the curved intensity profile either along the non-rounded outer edge or through the glass along a scan path to form on the glass substrate a rounded outer edge having a radius of curvature RE that is smaller than the first and second local radii of curvature RA and RB. The radius of curvature RE can be adjusted by changing a beam angle between the first and second Airy beams.

  • Publication number: 20190324592
    Abstract: Pressure-sensing touch systems and methods are disclosed for sensing the occurrence of a touch event based on pressure applied at a touch location. The touch system includes a light-source system and a detector system operably adjacent respective input and output edges of a waveguide. Pressure at a touch location on the waveguide gives rise to a touch event causes the waveguide to bend or flex. The waveguide bending causes a change in the optical paths of light traveling by FTIR, causing the light distribution in the output light to change. The changes are detected and are used to determine whether a touch event occurred, as well as the time-evolution of the touch event. The changes in the output light can include polarization changes caused by birefringence induced in the waveguide by the applied pressure applied. Various detector configurations are disclosed for sensing the location and pressure of a touch event.

  • Patent number: 10197732
    Abstract: Methods of forming ion-exchanged waveguides in glass substrates are disclosed. In one embodiment, a method of forming a waveguide in an ion-exchanged glass substrate having an ion-exchanged layer extending from a surface to a depth of layer of the ion-exchanged glass substrate includes locally heating at least one band at the surface of the ion-exchanged glass substrate to diffuse ions in the ion-exchanged layer within the at least one band. A concentration of ions within the at least one band is less than a concentration of ions outside of the at least one band, and at least one waveguide is defined within the ion-exchanged layer adjacent the at least one band. In some embodiments, the at least one waveguide is embedded within the ion-exchanged glass substrate such that an upper surface of the at least one waveguide is below the surface of the glass substrate by a depth d.
