Stabilization of higher-order vortices and multi-hump solitons in media with synthetic nonlocal nonlinearities
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We address the evolution of higher-order excited states, such as vortex and multi-hump solitons, in nonlocal media with synthetic, competing focusing and defocusing nonlinearities…
Gap solitons on a ring
Yaroslav V. Kartashov, Boris A. Malomed, Victor A. Vysloukh +1
We introduce a new species of gap solitons (GSs) supported by an azimuthally modulated guiding ring in defocusing cubic media. The periodicity in the azimuthal direction strongly m…
Power-dependent shaping of vortex solitons in optical lattices with spatially modulated nonlinear refractive index
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We address vortex solitons supported by optical lattices featuring modulation of both the linear and nonlinear refractive indices. We find that when the modulation is out-of-phase…
Nonlinear photonic crystals near the supercollimation point
Zhiyong Xu, Bjorn Maes, Xunya Jiang +3
We uncover a strong coupling between nonlinearity and diffraction in a photonic crystal at the supercollimation point. We show this is modeled by a nonlinear diffraction term in a…
Soliton modes, stability, and drift in optical lattices with spatially modulated nonlinearity
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We put forward new properties of lattice solitons in materials and geometries where both, the linear refractive index and the nonlinearity are spatially modulated. We show that the…
Propagation of solitons in thermal media with periodic nonlinearity
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We address the existence and properties of solitons in layered thermal media made of alternating focusing and defocusing layers. Such structures support robust bright solitons even…
