Abstract

An optical soliton is a stationary nonlinear pulse which propagates in a monomode fiber in the presence of a (anomalons) dispersion. The existence of soliton in a glass fiber was predicted by Hasegawa and Tappert [1] in 1973 and was experimentally demonstrated by Mollenauer et al. [2] in 1980. The balancing power P_o for formation of a soliton is inversely proportional to the square of the pulse width 2t_o and proportional to the group dispersion λ^2∂2n/∂λ² (<0)°, [3], where ω_o is the angular frequency of the carrier and S is the cross sectional area of the core.
