Effect of Twisting Phases on the Polarization Dynamics of a Vector Optical Field

Photonics, 2022
The effect of twisting phases on the polarization dynamics of a vector vortex beam with a spatially variant state of polarization (SoP) is investigated theoretically and experimentally.

Interferometry with Vortices

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.

Modulation of orbital angular momentum of vortex beam based on ordered pinhole screens

Results in Physics, 2023
Optical vortex phase beams have unique amplitudes and phase distributions, rendering them sensitive to the position and symmetry of modulating structures. This sensitivity can facilitate their applicability to optical communications.

Chiral nanoemitter array: A launchpad for optical vortices [PDF]

, 2013
A chiral arrangement of molecular nanoemitters is shown to support delocalised exciton states whose spontaneous decay can generate optical vortex radiation. In contrast to techniques in which phase modification is imposed upon conventional optical beams,

Stability of small amplitude normal modes of a Bose-Einstein condensate with a singly quantized vortex confined in an optical lattice

, 2004
We study the dynamics of a BEC with a singly quantized vortex, placed in the combined potential of a 1-D (2-D) optical lattice and an axi-symmetric harmonic trap.

Vortex preserving statistical optical beams

Optics Express, 2020
We establish a general form of the cross-spectral density of statistical sources that generate vortex preserving partially coherent beams on propagation through any linear ABCD optical system. We illustrate our results by introducing a class of partially coherent vortex beams with a closed form cross-spectral density at the source and demonstrating the

Integrated optical vortex beam receivers [PDF]

Optics Express, 2016
A simple and ultra-compact integrated optical vortex beam receiver device is presented. The device is based on the coupling between the optical vortex modes and whispering gallery modes in a micro-ring resonator via embedded angular gratings, which provides the selective reception of optical vortex modes with definitive total angular momentum ...
