Probing the dispersive properties of optical fibers with an array of femtosecond-written fiber Bragg gratings [PDF]
arXiv, 2021 We propose an efficient method to determine the effective refractive index of step-index optical fibers from the visible to the mid-IR and thus allowing to infer their dispersive properties over a broad spectral range. The validity of the method, based on the writing of an array of fiber Bragg gratings (FBGs) with known periods using the fs scanning ...
