  • 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.
    Type: Application
    Filed: October 20, 2017
    Publication date: February 15, 2018
