Individual space-variant waveplate model for generating full Poincaré beams and its stress engineering implementation

Optical Engineering: The Journal of SPIE
. Full Poincaré beams have application value in various optical technologies due to their diverse polarization distribution forms. It will be of great significance for promoting the application research of this kind of beam if there is an individual ...

Full Poincaré beam delineation based on the Stokes vortex ring

Journal of Optics, 2021
Axial and lateral polarization gradients in optical beams that can be created by counter/co-propagating fields have many applications including atom optics and optical lattices.

Nonlinear Mode Stabilization of Full-Poincaré Beams in Atmospheric Turbulence

Conference on Lasers and Electro-Optics
We discuss a regime of stable nonlinear propagation of a high-powered laser beam with a full-Poincaré polarization structure through atmospheric turbulence, enabling higher power transfer to distant localized areas.

Topological reconfiguration of full Poincaré beams via spin-decoupled metasurfaces

Photonics Europe
Analogous to their solid-state equivalents, optical beams exhibiting skyrmionic textures in the Stokes vector have recently attracted growing interest owing to their intrinsic topological robustness and distinctive polarization characteristics.

Full Poincaré beam with all the Stokes vortices.

Optics Letters, 2019
In this Letter, we present a recipe for the generation of full Poincaré beams that contain all Stokes vortices (SVs), namely ϕ12, ϕ23, and ϕ31 vortices.

An On-Chip Full Poincaré Beam Emitter Based on an Optical Micro-Ring Cavity

Conference on Lasers and Electro-Optics, 2019
We numerically demonstrate an on-chip full Poincaré beam emitter. We employ a micro-ring resonator augmented with scatterer arrays, which synthesizes the Poincaré beam as a superposition of twisted beams carrying different orbital-and spin-angular ...

Nondiffracting and self-healing properties of a multi-periodic full Poincaré beam.

Optics Letters
In recent years, structured beams have emerged as an attractive and promising area of research, and nondiffracting beams and vector beams stand out as two particularly important categories of structured beams.
