Abstract

Chirped fiber gratings have been the subject of considerable interest in the last few years as potential dispersion compensators, as they are compact, passive, and relatively simple to fabricate. So far, grating-compensated transmission over distances up to 270 km (for a 12-cm-long grating) have been reported for 10 Gbit/s systems.^1-3 Recently, we have introduced a new method—the moving fiber/phase-mask-scanning beam technique—for making good quality apodized and/or chirped fiber gratings,^4,5 and in this paper we report on the use of a 10-cm-long apodized chirped fiber grating made by this method for dispersion compensation of up to 400 km of nondispersion-shifted fiber at 10 Gbit/s.
