Reduction of the dispersive wave in periodically amplified links with initially chirped solitons

Abstract

It is shown that a prechirping of the input solitons can reduce the dispersive wave created by the focal mismatch between linear and nonlinear effects on a link with large amplifier spacing (Z/sub A//spl ges/50 km) and a small dispersion length (Z/sub c/<Z/sub A/). This technique is shown to be compatible with the chirped (bandwidth limited) amplification and to increase its domain of application.
