Abstract
A theoretical and experimental analysis of group velocity reduction in periodic super-structured Bragg gratings is presented. Experimental demonstration of group velocity reduction of sub-nanosecond pulses at the 1.5 μm wavelength of optical communications is reported using either a 20-cm-long Moiré and a periodically-spaced π phase shift fiber gratings. Time delays up to ∼ 690 ps for 250-ps-duration optical pulses have been achieved leading to the realization of an optical buffer.
