Efficient optical trapping with cylindrical vector beams
Optics Express, 2019 Radially and azimuthally polarized beams can create needle-like electric and magnetic fields under tight focusing conditions, respectively, and thus have been highly recommended for optical manipulation. There have been reports on the superiority of these beams over the conventional Gaussian beam for providing a larger optical force in single beam ...

Generation of cylindrical and elliptical symmetrical vector beam on the Mach–Zehnder interferometer
AIP Advances, 2018 We propose a principal scheme to generate the cylindrical and the elliptical symmetrical vector beam based on a modified Mach-Zehnder interferometer. The modified Mach-Zehnder interferometer, the wave plates, the Polarizing Beam Splitter (PBS) and the ...

Polarization-Selective Holographic Metasurface For Creating Cylindrical Vector Beams
IEEE Photonics Journal, 2019 Generalized cylindrical vector beams (GCVB) are spatially polarization inhomogeneous. It could be considered as a combination of a radially polarized beam and an azimuthally polarized beam with different weighting factors.

The evanescent wavefield part of a cylindrical vector beam
Optics Express, 2013 The evanescent wave of the cylindrical vector field is analyzed using the vector angular spectrum of the electromagnetic beam. Comparison between the contributions of the TE and TM terms of both the propagating and the evanescent waves associated with the cylindrical vector field in free space is demonstrated.
