Formation of chirped kink similaritons in non-Kerr media with varying Raman effect

Abstract

We study the formation of chirped kink similaritons in an optical transmitting non-Kerr medium under the influence of the Raman effect. The requirements concerning the optical material parameters for the existence of these propagating nonlinear waveforms are found. We show that such similariton structures are chirped linearly and that the chirping parameter allows us to control their dynamics efficiently. We also investigate the dynamical behaviors of these chirped self-similar pulses in both dispersion decreasing fiber and the periodic distributed amplification system.
