    How to process fiber optic gratings

    Understanding these gratings begins with a solid grasp of optical fiber properties and the functionality of the gratings themselves. This technology relies on periodic structures within optical fibers that modify the propagation of light, enabling a myriad of applications ranging from telecommunications to environmental. One of the particularly useful applications of a direct-write method is for the fabrication of fiber Bragg gratings (FBGs). In this report, modeling and experimental results are presented for three fiber Bragg gratings that were fabricated in Newport F-SMF-28 fiber with the direct-write method. This treated area functions like a specialized mirror, reflecting a specific wavelength of light while allowing all other wavelengths to pass through. Interferometers can be used to measure small phase changes in light.
