Alteration of the soliton behavior in silica-fibers doped with passive resonant atoms

Ve Itav€' numerically studied for the first time the full dy. namics describing the pulse propagation phenomenon in single-mode silica.fibers doped \Vith pa.ssive resonant two level atoms. For the specific case of a 3-order solitoll we show that the inclusion of the resonallt 11011- linearities destroys the fundamental characteristics of the pulse soliton behavior.
