Formation and stability of vortex solitons in nematic liquid crystals
Pawel S. Jung, Yana V. Izdebskaya, Vladlen G. Shvedov +2
We study the propagation dynamics of bright optical vortex solitons in nematic liquid crystals with a nonlocal reorientational nonlinear response. We investigate the role of optica…
Topological monopoles and currents in electromagnetic waves
Vladlen Shvedov, W. Krolikowski
Singularities, i.e. places of discontinuities of parameters are extremely general objects appearing in electromagnetic waves and thus are the key to understanding fundamental wave…
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…
Natural shaping of the cylindrically polarized beams
Vladlen Shvedov, Tatyana Fadeyeva, Nataliya Shostka +2
We have experimentally and theoretically shown that the circularly polarized beam bearing singly charged optical vortex propagating through a uniaxial crystal can be split after fo…
Materials processing with tightly focused femtosecond vortex laser beams
Cyril Hnatovsky, Vladlen G. Shvedov, Wieslaw Krolikowski +1
This letter is the first demonstration of material modification using tightly focused femtosecond laser vortex beams. Double-charge femtosecond vortices were synthesized with the p…
Materials processing with a tightly focused femtosecond vortex laser pulse
Cyril Hnatovsky, Vladlen G. Shvedov, Wieslaw Krolikowski +1
This letter is the first demonstration of material modification using tightly focused femtosecond laser vortex beams. Double-charge femtosecond vortices were synthesized with the p…
