Continuously self-focusing and continuously self-defocusing two-dimensional beams in dissipative media
Using the Lagrangian formalism, with a simple trial function for dissipative optical two-dimensional 2D soliton beams, we show that there are two disjoint sets of stationary soliton solutions of the complex cubicquintic Ginzburg-Landau equation, with concave and convex phase profiles, respectively. These correspond to continuously self-focusing and continuously self-defocusing types of 2D solit...
متن کاملTransformations of continuously self-focusing and continuously self-defocusing dissipative solitons.
Dissipative media admit the existence of two types of stationary self-organized beams: continuously self-focused and continuously self- defocused. Each beam is stable inside of a certain region of its existence. Beyond these two regions, beams loose their stability, and new dynamical behaviors appear. We present several types of instabilities related to each beam configuration and give examples...
متن کاملSelf-Trapping of “Necklace” Beams in Self-Focusing Kerr Media
Solitons in Kerr media are the most well-studied solitons in nature. The reason for that is twofold. First, the Kerr nonlinearity can be found in many systems: It represents a weak symmetric anharmonicity, which is equivalent to a weak saturation in a simple harmonic oscillator. For electromagnetic waves propagating in a weakly nonlinear centrosymmetric dielectric media, the Kerr nonlinearity m...
متن کاملThree-dimensional vortex solitons in self-defocusing media.
We demonstrate that families of vortex solitons are possible in a bidispersive three-dimensional nonlinear Schrödinger equation. These solutions can be considered as extensions of two-dimensional dark vortex solitons which, along the third dimension, remain localized due to the interplay between dispersion and nonlinearity. Such vortex solitons can be observed in optical media with normal dispe...
متن کاملOptically induced photovoltaic self-defocusing-to-self-focusing transition.
We show theoretically and experimentally that the photovoltaic nonlinearity that gives rise to spatial solitons can be switched from self-defocusing to self-focusing (or vice versa) by use of background illumination. This raises the possibility of bright photovoltaic solitons in LiNbO(3) .
