摘要

A unified analysis of all existing solitary wave solutions of the cubic-quintic nonlinear Schroedinger equation is made concretely considering a monomode step-index optical fibre with third- and fifth-order nonlinearities in the anomalous dispersion frequency region. Different aspects of the saturation effect due to the fifth-order nonlinearity, such as solitary wave propagation and bistability, are considered. All results obtained are directly applicable to the cases of spatial solitons and optical beam self-action in highly nonlinear media. The possible applications in optical switching experiments and communication systems are discussed. (author). 34 refs, 6 figs. (Atomindex citation 26:067938)
