Bragg gratings, refractive index profile, optical fibers


This work presents a method for obtaining the recording profile of fiber optic Bragg gratings. The modulation pattern is obtained with the aid of metallic and dielectric targets (Gold, Nickel, Aluminum and Poly-metil-metacrylate) positioned at the focal point of the recording interferometer. For the used 266 nm light the determined profile's envelope is irregular and the modulation period is within the expected 0.5 micrometer range. The results permit to use the method as an important tool in the optimization of the writing process of Bragg gratings in optical fibers.
