Dynamic modulation of Poincaré beams

, 2017
Generation of complex Poincaré beams is enabled by amplitude and phase modulation accompanied by simultaneous spatially polarization structuring. A holographic system to tailor complex light fields and optical angular momentum structures forecasts ...

Non-uniformly totally polarized beams with invariant polarization pattern in media with natural optical activity [PDF]

EPJ Web of Conferences
Non-uniformly and totally polarized (NUTP) beams have been proved to be useful in polarimetry, because they make faster and more accurate the determination of the Mueller matrix of sample.

Generalized Poincaré Beams in Tight Focus

, 2023
We study the tight focus of generalized (hybrid) Poincaré beams. A conventional Poincaré beam is a coaxial superposition of two optical vortices, one with left circular polarization and a topological charge (TC) of m, while the other has a right circular

Seeing full vectorial structures of light fields with a single-shot holographic multiplexed detector [PDF]

APL Photonics
The vectorial structure of light—amplitude, phase, and polarization—encodes essential information for applications ranging from super-resolution microscopy to high-capacity communications and quantum information processing.

Dynamic spin-polarization control of terahertz waves in magnetized plasmas [PDF]

Matter and Radiation at Extremes
Controlling terahertz (THz) polarization with high stability and tunability is essential for achieving further progress in ultrafast spectroscopy, structured-light manipulation, and quantum information processing.

Polarization smoothing based on full Poincaré beams modulated by stress-engineered optics.

Optics Express
In laser-driven inertial confinement fusion (ICF) facilities, nonuniform laser irradiation can cause significant challenges, such as hydrodynamics instability and laser plasma instability, which hinder the success of fusion.

Full vectorial feature of second-harmonic generation with full Poincaré beams

Chinese Optics Letters (COL), 2019
We demonstrate the full vectorial feature of second-harmonic generation (SHG), i.e., from infrared full Poincare beams to visible full Poincare beams, based on two cascading type I phase-matching beta barium borate crystals of orthogonal optical axes. We

Analytic treatment of nonparaxial full-Poincaré fields: singularity structure and trapping properties

Journal of Optics, 2021
An analytic extension to the nonparaxial regime of the full-Poincaré (FP) beams is presented. Instead of the stereographic mapping used in the paraxial case, these FP fields are defined in terms of a mapping from the polarization Poincaré sphere onto the

Analysis of the Errors in Polarimetry with Full Poincarè Beams

2019 PhotonIcs & Electromagnetics Research Symposium - Spring (PIERS-Spring), 2019
The main error sources of a recently proposed Mueller matrix polarimetric method based on the use of full Poincaré beams (FPBs) are described and analysed in detail.

Evolution of the polarization state and OAM-resolved polarization of full Poincaré beams propagating in the atmosphere.

Optics Express
A detailed study is conducted on the polarization characteristics of full Poincaré beams (FPBs) propagating through atmospheric turbulence, including polarization state, degree of polarization, OAM-resolved Stokes parameters, and OAM-resolved degree of ...
