en The Pulse Compression of Second- Order Dark Solitons تخصصی Special پژوهشي Research In this paper with considering dispersion coefficient and period normal length, pulse compression 2-order solitons in nonlinear fiber optics is investigated. In our numerical simulation we have used optical dark solitons because of its more stability in presence of noise as compared optical bright solitons.
