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 ...

Geometric Progression of Optical Vortices
Photonics, 2022 We study coaxial superpositions of Gaussian optical vortices described by a geometric progression. The topological charge (TC) is obtained for all variants of such superpositions. The TC can be either integer or half-integer in the initial plane. However,

Propagable Optical Vortices with Natural Noninteger Orbital Angular Momentum in Free Space
Advanced Photonics Research, 2023 Light beams with optical vortices can propagate in free space only with integer orbital angular momentum. Herein, this scientific consensus theoretically and experimentally is upheaved by proposing light beams carrying natural noninteger orbital angular ...

Orbital angular momentum and topological charge of a Gaussian beam with multiple optical vortices [PDF]
Компьютерная оптика, 2020 Here we study theoretically and numerically a Gaussian beam with multiple optical vortices with unitary topological charge (TC) of the same sign, located uniformly on a circle.

International Journal of Optics, 2012 Interference of optical beams with optical vortices is often encountered in singular optics. Since interferometry makes the phase observable by intensity measurement, it brings out a host of applications and helps to understand the optical vortex.

All-fiber SWAP-CNOT gate for optical vortices
Компьютерная оптика, 2021 We study the propagation of optical vortices in a system which consists of a tandem of a multi-helical and twisted anisotropic fiber. We show that at certain resonance regimes of the optical fibers such a system allows one to control sign flipping of the

Frame dragging with optical vortices [PDF]
, 2011 General Relativistic calculations in the linear regime have been made for electromagnetic beams of radiation known as optical vortices. These exotic beams of light carry a physical quantity known as optical orbital angular momentum (OAM).
