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.
