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 ...

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

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

Generation of optical vortices imitating water vortices
, 2022 In optics, we can generate vortex beams using specific methods such as spiral phase plates or computer generated holograms. While, in nature, it is worth noting that water can produce vortices by a circularly symmetrical hole. So, if a light beam can generate vortex when it is diffracted by an aperture? Here, we show that the light field in the Fresnel

Quadrupole absorption rate for atoms in circularly-polarized optical vortices
Results in Physics, 2021 Twisted light beams, or optical vortices, have been used to drive the circular motion of microscopic particles in optical tweezers and have been shown to generate vortices in quantum gases.
