Self-trapping of "necklace-ring" beams in self-focusing kerr media
Recently, we suggested a type of self-trapped optical beams that can propagate in a stable form in (2+1)D self-focusing Kerr media: Necklace-ring beams [M. Soljacic, S. Sears, and M. Segev, Phys. Rev. Lett. 81, 4851 (1998)]. These self-trapped necklaces slowly expand their ring diameter as they propagate as a result of a net radial force that adjacent "pearls" (azimuthal spots) exert on each ot...
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 کاملInteractions of Airy beams, nonlinear accelerating beams, and induced solitons in Kerr and saturable nonlinear media.
We investigate numerically interactions between two in-phase or out-of-phase Airy beams and nonlinear accelerating beams in Kerr and saturable nonlinear media in one transverse dimension. We discuss different cases in which the beams with different intensities are launched into the medium, but accelerate in opposite directions. Since both the Airy beams and nonlinear accelerating beams possess ...
متن کاملDynamics of self-trapped beams with phase dislocation in saturable Kerr and quadratic nonlinear media
We present a detailed stability analysis of oneand two-ring solitary waves with central phase dislocation in self-focusing saturable and quadratic nonlinear media. Varying parameters, we demonstrate transitions between different filamentation scenarios. An analytical approach is developed for the study of filament dynamics after ring breakup. Approximate expressions for the angular separation r...
متن کاملSolitons in Bragg Gratings with Saturable Nonlinearity
Coupled-mode equations for two waves coupled by the Bragg reflection in the presence of saturable nonlinearity are introduced. Stable solitons and their bound states fill a part of the bandgap, their collisions being quasi-elastic.
