Abstract

The article examines the stability of soliton-like solutions of the nonlinear Schrödinger equation with two types of nonlinear dependence of the dielectric constant on the electromagnetic-field strength. A multilayer structure of dielectric media obeying Kerr’s law and the saturation effect is considered, taking into account the absorption of part of the incident radiation by the medium. Numerical modeling is carried out to study the occurrence of the phenomenon of optical bistability and stability of wave propagation depending on the type of optical nonlinearity of the material.
