Abstract

Dark solitons¹ are characterized by an intensity dip on a continuous background, which propagates unaltered. Although a true continuous background wave may be impractical, it has been shown that dark pulses on a background pulse of finite width can propagate adiabatically as solitons.² Dark solitons have been observed in optical fibers by a few different experimental techniques³; however, the generation of the dark soliton trains from the interference and nonlinear copropagation of two delayed visible pulses in an optical fiber is numerically investigated.
