Extraction of Inherent Polarization Modes from an m‐Order Vector Vortex Beam
Advanced Photonics Research, 2022 Superposition of two independent orthogonally polarized beams is a conventional principle of creating a new light beam. Herein, it is intended to achieve the inverse process, namely, extracting inherent polarization modes from a single light beam ...

Achromatic vector vortex beams from a glass cone [PDF]
Nature Communications, 2016 AbstractThe reflection of light is governed by the laws first described by Augustin-Jean Fresnel: on internal reflection, light acquires a phase shift, which depends on its polarization direction with respect to the plane of incidence. For a conical reflector, the cylindrical symmetry is echoed in an angular variation of this phase shift, allowing us ...

Inverse Energy Flux in Tight Focusing of Vector Vortex Beam
Photonics, 2023 In this paper, we focus on the study of the negative energy flow in the tight focusing of a radially polarized vortex beam. We know that, because of the coupling of the polarization state and the vortex charge, the on-axis energy flow in the focal region

Hybrid generation and analysis of vector vortex beams
Applied Optics, 2017 A method is described for generating optical vector vortex beams carrying superpositions of orbital angular momentum states by using a tandem application of a spatial light modulator with a vortex retarder. The vortex component has a spatially inhomogeneous phase front that can carry orbital angular momentum, and the vector nature is a spatially ...

Purity of Vector Vortex Beams through a Birefringent Amplifier [PDF]
Physical Review Applied, 2018 Creating high-quality vector vortex (VV) beams is possible with a myriad of techniques at low power, and while a few studies have produced such beams at high-power, none have considered the impact of amplification on the vector purity. Here we employ novel tools to study the amplification of VV beams, and in particular the purity of such modes.
