Do optical quarks exist in free space: scalar treatment?
Alexander V. Volyar
We have considered new type of singular beams with fractional topological charges that were called the optical quarks possessed rather unique properties, their topological charges…
Polariton spectrum in nonlinear dielectric medium
Igor V. Dzedolik, O. Karakchieva
We obtain theoretically the phonon-polariton spectrum in nonlinear dielectric medium with the third order Kerr-type nonlinearity. We investigate the dependence of number of the pol…
Fractional optical vortices in a uniaxial crystal
T. A. Fadeyeva, A. F. Rubass, I. S. Valkov +1
We have analyzed the solutions to the vector paraxial wave equation in the unbounded uniaxial crystal in the form of the transverse electric (TE) and transverse magnetic (TM) mode…
Nonlinear polariton waves in dielectric medium
Igor V. Dzedolik, Olga Karakchieva
We theoretically investigate the properties of phonon-polariton inhomogeneous harmonic wave, cnoidal wave and spatial soliton propagating in boundless dielectric medium and compute…
Vector erf-Gaussian beams: fractional optical vortices and asymmetric TE and TM modes
T. Fadeyeva, C. Alexeyev, A. Rubass +1
We have considered the paraxial vector erf-Gaussian beams with field distribution in the form of the error function that are shaped by the cone of plane waves with a fractional ste…
Rotational spin Hall effect in a uniaxial crystal
Tatyana Fadeyeva, Constantine Alexeyev, Alexander Rubass +4
We have considered the propagation process of the phase-matched array of singular beams through a uniaxial crystal. We have revealed that local beams in the array are rotated when…
Subwave spikes of the orbital angular momentum of the vortex-beams in a uniaxial crystal
T. Fadeyeva, C. Alexeyev, A. Rubass +3
We have theoretically predicted the gigantic spikes of the orbital angular momentum caused by the conversion processes of the centered optical vortex in the circularly polarized co…
Nondiffracting vortex-beams in a birefringent chiral crystal
Tatyana A. Fadeyeva, Alexander V. Volyar
A vector wave analysis of nondiffracting beams propagating along a birefringent chiral crystal for the case of tensor character both of the optical activity and linear birefringenc…
The transverse shift of a high order paraxial vortex-beam induced by a homogeneous anisotropic medium
T. A. Fadeyeva, A. F. Rubass, A. V. Volyar
We consider the propagation of a tilted high order paraxial vortex-beam through a homogeneous anisotropic medium of a uniaxial crystal. We found that the initially circularly polar…
Quadrefringence of optical vortices in a uniaxial crystal
T. Fadeyeva, A. Rubass, Yu. Egorov +2
The splitting of a single optical vortex into four separate ones in a singular beam is theoretically and experimentally described for the propagation of light obliquely through a u…
Momentum transfer in a standing optical vortex
V. G. Shvedov
A field superposition of singular beams incident on, and then reflected from a mirror has been investigated. It was demonstrated that the standing optical wave, which contains a vo…
Focusing and correlation properties of white-light optical vortices
Vladlen Shvedov, Wieslaw Krolikowski, Alexander Volyar +3
We generate double-charge white-light optical vortices by sending a circularly polarized partially incoherent light through an uniaxial crystal. We show that the generated polichro…
