Abstract
Optical low coherence reflectometry (OLCR) is applied to the precise characterization of Bragg gratings in optical fibers. Grating with lengths below two millimeters have been fabricated in standard telecommunication fibers. Their OLCR spectra can be used to determine the induced index changes, which range from 0.64*10-3 to 1.16*10-3, with an accuracy of a few percent. These changes are obtained by adjusting the position of the oscillation minima in the OLCR spectra.Keywords
