Novel topological quasi-soliton solutions for the nonlinear cubic-quintic Schroedinger equation model

摘要

The methodology based on the quasi-soliton concept provides for a systematic way to discover an infinite number of the novel stable bright and dark soliton management regimes for the nonlinear cubic-quintic Schrodinger equation model with varying dispersion, nonlinearity and gain or absorption. Quasi-soliton solutions for this model must be of rather general character than canonical solitons of standard nonlinear Schrodinger equation model, because the generalized model takes into account the saturation nonlinear effect and arbitrary variations of group velocity dispersion, nonlinearity and gain or absorption. Novel topological and nontopological quasi-soliton solutions for the nonlinear cubic-quintic Schrodinger equation model have been discovered. It is shown that, today, the most attractive media to discover novel topological quasi-solitons are organic thin films and polymeric waveguides.
