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 mu m wavelength of optical communications is reported using either a 20-cm-long Moire and a periodically-spaced pi phase shift fiber gratings. Time delays up to similar to 690 ps for 250-ps-duration optical pulses have been achieved leading to the realization of an optical buffer.

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 mu m wavelength of optical communications is reported using either a 20-cm-long Moire and a periodically-spaced pi phase shift fiber gratings. Time delays up to similar to 690 ps for 250-ps-duration optical pulses have been achieved leading to the realization of an optical buffer.File in questo prodotto:
