Journal ArticleDOI
Single- and double-vortex vector solitons in self-focusing nonlinear media.
TL;DR: It is demonstrated that a large-amplitude guided mode can stabilize the ringlike vortex beam which usually decays due to azimuthal modulational instability and demonstrate both vortex bistability and mutual stabilization effect.
Journal ArticleDOI
Radiationless energy exchange in three-soliton collisions
TL;DR: It is explained why collisions between two kinks and one antikink are observed to be practically elastic or strongly inelastic depending on relative initial positions of the kinks, and the fact that the three-soliton collisions become more elastic with an increase in the collision velocity becomes clear in the framework of thethree-particle model.
Journal ArticleDOI
Switching of Discrete Optical Solitons in Engineered Waveguide Arrays
TL;DR: A simple concept for controlling nonlinear switching of discrete solitons in arrays of weakly coupled optical waveguides, for both cubic and quadratic nonlinear response, is demonstrated.
Journal ArticleDOI
Spiraling solitons and multipole localized modes in nonlocal nonlinear media
Daniel Buccoliero,Servando Lopez-Aguayo,Stefan Skupin,Anton S. Desyatnikov,Ole Bang,Wieslaw Krolikowski,Yuri S. Kivshar +6 more
TL;DR: In this paper, the propagation of rotating multi-soliton localized structures in optical media with spatially nonlocal nonlinearity is analyzed and it is shown that nonlocality stabilizes the azimuthal breakup of rotating dipole as well as multipole localized soliton modes.
Journal ArticleDOI
Discrete dissipative localized modes in nonlinear magnetic metamaterials
Nikolay N. Rosanov,N. V. Vysotina,A. N. Shatsev,Ilya V. Shadrivov,David A. Powell,Yuri S. Kivshar +5 more
TL;DR: In this paper, the existence, stability, and propagation of dissipative discrete localized modes in one and two-dimensional nonlinear lattices composed of weakly coupled split-ring resonators (SRRs) excited by an external electromagnetic field were analyzed.
