- Abstract
Delay ripples of chirped-fiber Bragg grating (CFBG), which can compensate 200-km-long fiber's dispersion, is detailedly analyzed. A numerical simulation of the delay ripple of cascaded gratings is done using Schrödinger's equation and is compared with an experiment using a 1000-km transmission system over G.652 fiber by five groups of CFBGs for dispersion compensation. The research shows that the system degradation depends on the delay-ripple period, which is 0.01–0.1 nm, and its amplitude. Fluctuation of the power penalty, which depends on the CFBG's ripple period when the source wavelength is changed ±20 GHz around the CFBG's center wavelength, is experimentally studied. The theoretical results agree well with the experimental results. © 2004 Wiley Periodicals, Inc.
