Mueller matrix polarimetry using full Poincaré beams

Optics and Lasers in Engineering, 2019
Full Poincare beams (FPBs) are proposed for polarimetric applications. Such beams present all states of totally polarized light across their transverse section at once and therefore can be considered as parallel polarization state generators.

Dynamic propagation of optical vortices embedded in full Poincaré beams with rotationally polarization symmetry

Optics Communications, 2015
Dynamical propagation characteristics of optical vortices embedded in Full Poincaré (FP) beams with rotationally polarization symmetry are studied in this paper to illustrate that polarization map alone does not provide a unique description of ...

Controlling the Coverage of Full Poincaré Beams through Second-Harmonic Generation

Physical Review Applied, 2023
Ideal full Poincaré (FP) beams contain all possible polarization states on the surface of the Poincaré sphere and are readily created by linear optical techniques and, more recently, by nonlinear optical processes. An inherent limitation in the latter is

Polarimetric method of generating full Poincaré beams within a finite extent.

Journal of The Optical Society of America A-optics Image Science and Vision, 2022
A novel polarimetric method of generating a variety of Poincaré beams such as half Poincaré beams and full Poincaré beams using doubly inhomogeneous wave plates (d-plates) is proposed.

Interferometric polarimetry using full-Poincaré beams

OPTO, 2021
A full-Poincare beam is an optical beam that contains every polarization state on the Poincare sphere over its cross-section. We present an interferometric method to measure the polarization state of a test beam by interfering it with a full-Poincare ...

The evolutions of spin density and energy flux of strongly focused standard full Poincaré beams

, 2020
Nonzero transverse spin density, which describes phenomenon in which the electromagnetic fields of localized light spin in a plane containing its wavenumber vector, has gained enormous interest recently because of its useful applications like spin ...
