Spin-orbit conversion at the sharp focus of a circularly polarized light beam

Компьютерная оптика
It is known that when tightly focusing a circularly polarized optical vortex, spin-to-orbital angular momentum conversion occurs. It is usually said that the longitudinal component of the spin angular momentum (SAM) vector is transformed into the ...

VECTOR VORTEX HOLOGRAPHIC GRATINGS INSCRIBED IN AZOBENZENE-CONTAINING POLYMER FILMS AND ITS DIFFRACTION FEATURES [PDF]

"Holographic vector vortex gratings are inscribed by the superposition of two orthogonal vector vortex beams subtending a small angle with respect to the normal vector of the photoanisotropic recording medium.

Simulated Lidar Signals for Wake Vortex Detection ahead of the Aircraft [PDF]

, 2012
Within the DLR-project “Wetter & Fliegen“ a feasibility study of airborne lidar sensors for active control at flying through wind shear and turbulent air masses (specifically wake vortices) was carried out.

Transverse and Longitudinal Energy Flows in a Sharp Focus of Vortex and Cylindrical Vector Beams

Applied Sciences
It is shown in this work that, with strong focusing of a beam with optical vortex and circular polarization, three energy flows take place in the focal plane: direct longitudinal, reverse longitudinal and azimuthal transverse flows. Calculations are made

The Propagation Characteristics of Circular Airy Beams with Propagational Fractional-Order Optical Vortices

Photonics
We investigate the propagation properties of circular Airy beams (CABs) with propagational fractional-order optical vortices (OVs). The superposition of the phase singularity and polarization singularity from a vortex vector beam (VVB) plays a ...

Vector vortex solitons in nematic liquid crystals [PDF]

, 2009
We analyze the existence and stability of two-component vector solitons in nematic liquid crystals for which one of the components carries angular momentum and describes a vortex beam. We demonstrate that the nonlocal, nonlinear response can dramatically
