In 1973, Hasegawa and Tappert predicted that the nonlinear refractive index of silica fibers can compensate for Group Velocity Dispersion GVD, resulting in the so-called optical solitons which propagate without distortion. Both bright and dark solitons were identified that correspond to the negative and positive GVD regions of the spectrum, respectively. Since then, owing to their potential applications in high bit-rate fiber telecommunication systems, optical solitons have been intensively investigated both theoretically and experimentally. Soliton propagation of bright pulses has been verified in a large number of experiments and the possibility of its application in long haul fiber transmission has been demonstrated.
