Optical Vortices shape Optical Tornados
Optics Express, 2023 We demonstrate that by seeding an accelerating ring-Airy beam with a finite number of off-axis optical vortices, it transforms into a Tornado wave (ToW) upon propagation. Using numerical simulations, we show that both the spiraling high-intensity lobes and the optical vortices exhibit angular acceleration and follow interwinding braid-like trajectories.

Polarization and topological mode dispersion of optical vortices in circular optical fibers [PDF]
Компьютерная оптика, 2019 In this paper we investigated a problem of intermode dispersion within a group of optical vortices with an azimuthal number greater than or equal to 1 in circular optical fibers.

The Mechanism of the Formation of the Spin Hall Effect in a Sharp Focus
Photonics, 2023 We have shown how the spin Hall effect is formed in a tight focus for two light fields with initial linear polarization. We have demonstrated that an even number of local subwavelength regions appear in which the sign of the longitudinal projection of ...

Laser Beam Positioning by Using a Broken-Down Optical Vortex Marker
Applied Sciences, 2021 We propose the use of high-order optical vortices as markers in the positioning of a laser beam. The broken optical vortices are arranged in constellations.

Optical vortices in antiguides [PDF]
Optics Letters, 2013 We address the question of whether an optical vortex can be trapped in a dielectric structure with a core of a lower refractive index than the cladding--namely an antiguide. Extensive numerical simulations seem to indicate that this inverse trapping of a vortex is not possible, at least in straightforward implementations.

Optical spatiotemporal vortices
eLight, 2023 AbstractSpatiotemporal vortices of light, featuring transverse orbital angular momentum (OAM) and energy circulation in the spatiotemporal domain, have received increasing attention recently. The experimental realization of the controllable generation of spatiotemporal vortices triggers a series of research in this field. This review article covers the

Evolutions of optical vortices under wide Gaussian background
Results in Physics, 2021 Analytically discussed is the evolution properties of optical vortices superimposed by Gaussian backgrounds. A kind of Tornado-like pattern is obtained after linear propagations, when the Gaussian background is wide enough compared with optical vortices.
