Gyrotropic Crystals as a Basis for Creation of Helical Polychromatic Singular Beams

Publikováno v: Photonics, Vol 10, Iss 9, p 1044 (2023)

In this work, studies are carried out in the field of optical singular beams that have passed through gyrotropic crystals. We have experimentally shown that singular beams with a helical intensity distribution are formed when passing through a system

Fine Structure of Optical Vortices in Linearly Polarized Laguerre–Gaussian Beams in Oblique Beams Propagating a Uniaxial Crystal

Autor: Yuriy Egorov, Alexander Rubass

Publikováno v: Photonics, Vol 10, Iss 6, p 684 (2023)

Traditional ideas about linearly polarized paraxial beam propagation along the optical axis of a uniaxial crystal suggest that at the crystal exit face, after propagation through the polarizer, the beam will form an intensity distribution in the form

Spin-Orbit Coupling in Quasi-Monochromatic Beams

Autor: Yuriy Egorov, Alexander Rubass

Publikováno v: Photonics, Vol 10, Iss 3, p 305 (2023)

We investigate the concept that the value of the spin-orbit coupling is the energy efficiency of energy transfer between orthogonal components. The energy efficiency changes as the beam propagates through the crystal. For a fundamental Gaussian beam,
