Optical vault: reconfigurable bottle beam by conically refracted light
A. Turpin, V. Shvedov, C. Hnatovsy +3
We employ conical refraction of light in a biaxial crystal to create an optical bottle for trapping and manipulation of particles. We show that by just varying the polarization of…
Nonlocal stabilization of nonlinear beams in a self-focusing atomic vapor
S. Skupin, M. Saffman, W. Krolikowski
We show that ballistic transport of optically excited atoms in an atomic vapor provides a nonlocal nonlinearity which stabilizes the propagation of vortex beams and higher order mo…
Modulational instability, solitons and beam propagation in spatially nonlocal nonlinear media
W. Krolikowski, O. Bang, N. I. Nikolov +4
We present an overview of recent advances in the understanding of optical beams in nonlinear media with a spatially nonlocal nonlinear response. We discuss the impact of nonlocalit…
Observation of dipole-mode vector solitons
Wieslaw Krolikowski, Elena A. Ostrovskaya, Carsten Weilnau +5
We report on the first experimental observation of a novel type of optical vector soliton, a {\em dipole-mode soliton}, recently predicted theoretically. We show that these vector…
Influence of four-wave mixing and walk-off on the self-focusing of coupled waves
L. Berge, O. Bang, W. Krolikowski
Four-wave mixing and walk-off between two optical beams are investigated for fo cusing Kerr media. It is shown that four-wave mixing reinforces the self-focusi ng of mutually-trapp…
