Discrete Cylindrical Vector Beam Generation from an Array of Optical Fibers [PDF]

open access: yesOptics Express, 2009
A novel method is presented for the beam shaping of far field intensity distributions of coherently combined fiber arrays. The fibers are arranged uniformly on the perimeter of a circle, and the linearly polarized beams of equal shape are superimposed ...

An all-fiber laser generating cylindrical vector beam

open access: yesOptics Express, 2010
We proposed and demonstrated an all-fiber laser to generate cylindrical vector beam. A pair of fiber-based collimators was used to select the cylindrical vector beam operating. The radially and azimuthally polarized modes can be switchable just by applying pressure to a section of fiber in our fiber laser system. A 70 cm long Yb-doped fiber was used as

Statistics properties of a cylindrical vector partially coherent beam

open access: yesOptics Express, 2011
Cylindrical vector partially coherent beam is introduced as a natural extension of cylindrical vector coherent beam based on the unified theory of coherence and polarization. Analytical propagation formula for the cross-spectral density matrix of a cylindrical vector partially coherent beam passing through paraxial ABCD optical system is derived based ...

Cylindrical vector beam generator using a two-element interferometer

open access: yesOptics Express, 2019
We realize a robust and compact cylindrical vector beam generator which consists of a simple two-element interferometer composed of a beam displacer and a cube beamsplitter. The interferometer operates on the higher-order Poincare sphere transforming a homogeneously polarized vortex into a cylindrical vector (CV) beam. We experimentally demonstrate the

Nonequilibrium Magnetic Oscillation with Cylindrical Vector Beams [PDF]

open access: yesScientific Reports, 2018
AbstractMagnetic oscillation is a generic property of electronic conductors under magnetic fields and widely appreciated as a useful probe of their electronic band structure, i.e. the Fermi surface geometry. However, the usage of the strong static magnetic field makes the measurement insensitive to the magnetic order of the target material.

Plasmonic oligomers in cylindrical vector light beams [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2013
We investigate the excitation as well as propagation of magnetic modes in plasmonic nanostructures. Such structures are particularly suited for excitation with cylindrical vector beams. We study magneto-inductive coupling between adjacent nanostructures.

Focusing fractional-order cylindrical vector beams

open access: yesComputer Optics, 2021
By numerically simulating the sharp focusing of fractional-order vector beams (0≤m≤1, with azimuthal polarization at m=1 and linear polarization at m=0), it is shown that the shape of the intensity distribution in the focal spot changes from elliptical (m=0) to round (m=0.5) and ends up being annular (m=1).

An interference scheme for generating inhomogeneously polarized laser radiation using a spatial light modulator [PDF]

open access: yesКомпьютерная оптика, 2020
An optical system for converting linearly polarized laser beams into cylindrical vector beams is developed and experimentally investigated. The scheme is based on the coherent addition of mode beams using a Mach-Zehnder interferometer. The simplicity and
