Research on spatially structured light has seen an explosion in activity over the past
decades, powered by technological advances for generating such light and driven by …

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 …

A nonlinear self-focusing material can amplify random small-amplitude phase modulations
present in an optical beam, leading to the formation of amplitude singularities commonly …

We report on the existence, stability and dynamical properties of two-dimensional self-
localized vortices with azimuthal numbers up to 4 in a simple model for lasers with frequency …

We demonstrate that strongly nonlocal nonlinear media can support two-dimensional
solitons in the form of rotating crescent vortices, which are generated by a superposition of …

We report the observation of single and multiple vortex solitons in a self-focusing dissipative
system, a broad-area vertical-cavity surface-emitting laser (VCSEL) with frequency-selective …

Multi-wave mixing gives rise to new frequency components due to the interaction of light
signals with a suitable nonlinear medium. In this book a systematic framework for the control …

We formulate and study dynamics from a complex Ginzburg–Landau system with saturable
nonlinearity, including asymmetric cross-phase modulation (XPM) parameters. Such …

We report the observation of multi-component dipole and vortex vector solitons composed of
eight coexisting four-wave mixing (FWM) signals in two-level atomic system. The formation …

In this article, I study a system of two incoherently coupled components in a nonlinear Kerr-
type photonic crystal fiber presenting angular momentum in one or both components. I …
