Optical trapping of gold nanoparticles by cylindrical vector beam

Optics Letters, 2012
Optical trapping of gold nanoparticles is experimentally demonstrated using radially and azimuthally polarized beams. The transverse optical trapping stiffness of gold nanoparticles is measured. The radially polarized beam exhibits a higher trapping efficiency than the azimuthally polarized beam and the Gaussian beam.

Approach to multiplexing fiber communication with cylindrical vector beams

Optics Letters, 2017
Cylindrical vector beams (CVBs), including radial, azimuthal, and hybrid polarization vortex states, are based on the polarization singularity and regarded as the eigenmodes of fiber. In this Letter, we propose and demonstrate CVB (de)multiplexing communication in a few-mode fiber (FMF). We simulate the eight CVB modes, including the ±1 orders and the ±

Three-dimensional focus shaping with cylindrical vector beams

Optics Communications, 2006
A three-dimensional focus shaping technique using the combination of cylindrical polarization with binary diffractive optical element is proposed. The energy density pattern at the vicinity of the focus can be tailored in three dimensions by appropriately adjusting the parameters of the cylindrical vector beam illumination, numerical aperture of the ...

Polarization and Propagation Behavior of Cylindrical Vector Beams

Frontiers in Optics 2013, 2013
Expressions for cylindrical vector beams, that also satisfy Maxwell equations are derived. Modified description of two cylindrically polarized beams Bessel-Gauss and Laguerre-Gauss are studied and their propagation and polarization properties are investigated.

Cylindrical Vector Beam Holography without Preservation of OAM Modes

Nano Letters
Orbital angular momentum (OAM) multiplexed holograms have attracted a great deal of attention recently due to their physically unbounded set of orthogonal helical modes. However, preserving the OAM property in each pixel hinders fine sampling of the target image in principle and requires a fundamental filtering aperture array in the detector plane ...
