Similaritons interaction in nonlinear graded-index waveguide amplifiers
Résumé
Self-similar propagation of optical beams inside a one-dimensional nonlinear graded-index waveguide amplifier is studied. By employing the lens-type and Husimi transformations, movable exact quasisoliton similaritons are obtained. Under certain conditions, these similaritons are well described by bright, Gaussian, and dark solitons on a compact parabolic background. Approximate but highly accurate analytical methods are developed to describe the interaction dynamics of exact quasisoliton similaritons.
