Abstract
Low-coherence interferometric measurements of dispersion in fibre Bragg gratings are presented. The group delay as a function of wavelength is obtained rapidly by Fourier-transform processing the interferogram, yielding results within a few minutes. The experimental repeatability is shown to be better than 1 ps.Keywords
