By solving numerically the extended nonlinear Schrodinger equation we investigate the influence of higher-order dispersion effects on the propagation of optical pulses in the normal dispersion regime in a highly nonlinear fiber. Already a small amoun

The Bloch and dipole oscillations of a Bose Einstein condensate (BEC) in an optical superlattice is investigated. We show that the effective mass increases in an optical superlattice, which leads to localization of the BEC, in accordance with recent

In this paper possibilities of a stabilization of large amplitude fluctuations in an intracavity-doubled solid-state laser are studied. The modification of the cross-saturation coefficient by the effect of spatial hole-burning is taken into account.

We consider two coupled nonlinear Schrodinger equations, the (1 + 1) and the (2 + 1)-dimensional and concentrate basically on the question as to whether there exists a stable, self-trapped solution. The positive answer is obtained within the variatio

Properties of two pulses propagating simultaneously in different dispersion regimes, anomalous and normal, in a Kerr-type planar waveguide are studied in the framework of the nonlinear Schroedinger equation. Catastrophic self-focusing and spatio-temp

A numerical study of the properties of Gaussian pulses propagating in a planar waveguide under the combined effects of positive Kerr-type nonlinearity, diffraction in planar waveguides and anomalous or normal dispersion, is presented. It is demonstra

While usually the generation of a Stokes component is attributed to Raman scattering, we present here experimentally and numerically a mechanism which can be explained by the nonlinear Schrodinger equation alone. It can be employed to excite new freq

Summary form only given. Two optical pulses propagating simultaneously in a planar waveguide with positive Kerr-type nonlinearity and anomalous dispersion are considered. It is assumed that duration of first (second) pulse, referred here to as the sh
