"Spin" and "Orbital" Flows in a Circularly Polarized Paraxial Beam: Orbital Rotation without Orbital Angular Momentum
A. Ya. Bekshaev
In light beams with circular or elliptic polarization, the transverse energy flow consists of the "spin" and "orbital" parts. Both of them can induce the orbital motion of micropar…

High-angle diffraction of a Gaussian beam by the grating with embedded phase singularity
A. Bekshaev, O. Orlinska, M. Vasnetsov
Spatial characteristics of the optical-vortex (OV) beams created during the Gaussian beam diffraction by a grating with groove bifurcation are analyzed theoretically and numericall…

Structure of optical vortices produced by holographic gratings with "fork" geometry: Kummer beams
A. Ya. Bekshaev, A. I. Karamoch, M. V. Vasnetsov +2
Holographic gratings with topological defects (branching of one or more fringes) are widely used for generating light beams with optical vortices (OV). This work presents an analys…
