Optical trapping of nanotubes with cylindrical vector beams
Optics Letters, 2012 We use laser beams with radial and azimuthal polarization to optically trap carbon nanotubes. We measure force constants and trap parameters as a function of power showing improved axial trapping efficiency with respect to linearly polarized beams.

Cylindrical vector beam-splitters
Frontiers in Optics 2011/Laser Science XXVII, 2011 We show that radial and azimuthal polarizations can be separated with a circular sub-wavelength grating. The proposed grating-based beam-splitter can be used to generate cylindrical vector beams from circularly polarized light.

Focusing of high order cylindrical vector beams
Journal of Optics A: Pure and Applied Optics, 2009 We present the results of calculations of focusing high order cylindrical vector beams in the limit of high numerical aperture. We derive a form of the vectorial diffraction integrals for arbitrary radial and azimuthal mode indices and evaluate these numerically for a number of different modes.

Coherent beam combining of cylindrical vector beams for power scaling
Optics Letters, 2023Coherent beam combining (CBC) of cylindrical vector beams (CVBs) based on an active phase controller is proposed and demonstrated. Experimentally, two pieces of spatially variant wave plates (S-wave plate) were employed as vector mode convertors for two individual 1064-nm fiber amplifier channels.

Concentric microcavities for cylindrical vector beam lasers
Optics Letters, 2020Cylindrical vector (CV) beams with polarization singularities have attracted intense research interest because of their important applications in optical trapping and manipulation, imaging, and high-speed optical communication. In this Letter, we propose a high-speed integrated device designed to emit fundamental CV beams, including both radially and ...

Cylindrical vector beams for wireless power transfer
2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017This article investigates wireless power transfer in the Fresnel zone using cylindrical vector beams. First, a generalized coupling coefficient between two circular apertures in the Fresnel zone is derived. From the generalized coupling coefficient, explicit coupling coefficients between two circular (focused or unfocused) apertures supporting Gaussian,
