Dispersion-less square filter fibre Bragg gratings for 25GHz DWDM-channel separations are demonstrated. The filters show a useful bandwidth of 75% and reflectivity in excess of 99.9%. We test the gratings at 10Gbit/s and demonstrate that they at no point in the stop-band are limited by dispersion-induced distortion.
