Journal ArticleDOI
Cylindrical vector beams: from mathematical concepts to applications
TL;DR: An overview of the recent developments in the field of cylindrical vector beams is provided in this paper, where the authors also discuss the potential of using these beams in other fields.
Journal ArticleDOI
Trapping metallic Rayleigh particles with radial polarization
TL;DR: Numerical studies show that optical tweezers using radial polarization can stably trap metallic particles in 3-dimension due to the spatial separation of the gradient force and scattering/absorption forces.
Journal ArticleDOI
Focus shaping using cylindrical vector beams
Qiwen Zhan,James R. Leger +1 more
TL;DR: A focus shaping technique using generalized cylindrical vector beams that can be tailored by appropriately adjusting the rotation angle to obtain peak-centered, donut and flattop focal shapes is reported.
Journal ArticleDOI
Plasmonic Lens Made of Multiple Concentric Metallic Rings under Radially Polarized Illumination
TL;DR: The experimental confirmation of the focusing properties and field enhancement effect of plasmonic lens made of multiple concentric annular rings using a collection mode near field scanning optical microscope.
Journal ArticleDOI
Propagation of vector vortex beams through a turbulent atmosphere
TL;DR: The existence of the vectorial vortex can be identified with longer propagation distance than the scalar vortex even with vanishing characteristic vortex structure in the irradiance images, indicating the potential advantages of using a vector vortex beam to mitigate atmospheric effects and enable a more robust free space communication channel with longer link distance.
