  • Fiber Bragg Gratings in Carbon-Coated Optical Fibers and Techniques for Making Same
    Publication number: 20180044234
    Abstract: A technique is described for fabricating one or more optical devices in a carbon-coated optical fiber. A photosensitive optical fiber is provided having a hermetic carbon coating. Further provided is a laser having a beam output that is configured to inscribe one or more refractive index modulations into the optical fiber through the hermetic carbon layer while leaving the hermetic carbon layer intact. The laser is used to inscribe one or more optical devices into the optical fiber through the hermetic carbon layer.

  • LOW REFRACTIVE INDEX COATING FOR OPTICAL FIBERS, METHODS OF MANUFACTURE THEREOF AND ARTICLES COMPRISING THE SAME
    Publication number: 20160369103
    Abstract: Disclosed herein is a composition comprising 65 to 95 weight percent of a fluorinated monofunctional monomer; 5 to 35 weight percent of a fluorinated multifunctional monomer; and 0.5 to 3 weight percent of a silane coupling agent; where all weight percents are based on the total weight of the composition; where the fluorinated monofunctional monomer and the fluorinated multifunctional monomer are devoid of any trifunctional fluorocarbon moieties when they have 6 or more fluorocarbon repeat units; where the fluorocarbon repeat units are CF2 or CF moieties; and where a crosslinked composition has a shore D hardness of 56 to 85 and has a refractive index (RI) that meets the limitation of the equation RI?1.368+10.8/X, where X denotes wavelength in nanometers.

  • Formation of gratings in polymer-coated optical fibers
    Patent number: 5620495
    Abstract: Recognizing the rate-determining nature of the coating removal and recoating steps, applicants have demonstrated that with proper combination of low absorbing polymer, glass and low intensity radiation, UV-induced gratings can be side-written into polymer coated fibers without removing the polymer, thus permitting up the possibility of high speed fabrication of fiber gratings.
