  • Method and apparatus for applying a mid-IR graded-index microstructure to an optical fiber tip to achieve anti-reflective properties
    Patent number: 9533911
    Abstract: A method and apparatus for applying a mid-IR graded microstructure to the end of a chalcogenide glass optical fiber are presented herein. The method and apparatus transfer a microstructure from a negative imprint on a nickel shim to a chalcogenide glass fiber tip with minimal shape distortion and minimal damage-threshold impact resulting in large gains in anti-reflective properties.
    Type: Grant
    Filed: July 22, 2014
    Date of Patent: January 3, 2017
    Assignee: BAE Systems Information and Electronic Systems Integration Inc.
    Inventors: Joseph M. Owen, David P. Kelly, Michael E. Chadwick
