The propagation characteristics of chirped Gaussian pulses in fibers with 5 different group dispersion profiles are theoretically deduced and the effects of the initial chirps on the pulse width discussed.Compared with conventional Single Mode Fibers(SMF)
the pulse broadening in these five Dispersion-Decreasing Fibers(DDF) is effectively restrained to be slow with fairly big differences among themselves.As for the effects of the initial chirps on the pulses
when β2c>0
the pulse broadening is faster than that without chirps
while when β2c <0
the pulses are fast broadened after an initial process of narrowing.
