Solitons, nonlinear self-trapped wavepackets, have been extensively studied in many and
diverse branches of physics such as optics, plasmas, condensed matter physics, fluid …

We provide an overview of recent experimental and theoretical developments in the area of
optical discrete solitons. By nature, discrete solitons represent self-trapped wavepackets in …

The current research into solitons and their use in fiber optic communications is very
important to the future of communications. Since the advent of computer networking and …

In the course of the past several years, a new level of understanding has been achieved
about conditions for the existence, stability, and generation of spatiotemporal optical …

We present an experimental study on wave propagation in highly nonlocal optically
nonlinear media, for which far-away boundary conditions significantly affect the evolution of …

In physics, wave propagation is traditionally analyzed by means of regular solutions of wave
equations. However, solutions of wave equations in two and three dimensions often possess …

We report on the first experimental observation of discrete vortex solitons in two-dimensional
optically induced photonic lattices. We demonstrate strong stabilization of an optical vortex …

Vortices are topological objects representing the circular motion of a fluid. With their
additional degree of freedom, the vorticity, they have been widely investigated in many …

We show that an azimuthally periodically modulated bright ring “necklace” beam can self-
trap in self-focusing Kerr media and can exhibit stable propagation for very large distances …

“Dark beams” are nonuniform optical beams that contain either a one-dimensional (1D) dark
stripe or a two-dimensional (2D) dark hole resulting from a phase singularity or an amplitude …
