Based on the dispersion-compensation fiber (DCF),the dispersion-shift fiber (DSF) and erbium-doped nonlinear amplifying fiber loop mirror (ED-NALM),a novel designed model of the optical pulse compression to the chirped pulse generated from gain-switched distributed feedback (GS-DFB) se miconductor laser was presented.The numerical simulations reveal that a chirped optical pulse with 30ps full-width in half maximum generated from GS-DFB semic onductor laser can be compressed to a pedestal-free pulse with 180fs full-width.
