Effect of polarization on transport of particles in air by optical vortex beam

Eckerskorn, Niko; Zheng, Nina; Shvedov, Vladlen; Rode, Andrei V; Krolikowski, Wieslaw


Experiments on transport of spherical particles in air by optical vortex beam show that the speed of transport depends drastically on light polarization. There is a clear correlation between the speed of particle transport in a pipeline formed by cross-polarized vortices: a horizontally polarized beam moves particles faster than a vertically polarized one. To elucidate this effect we demonstrate, both in theory and experiments, that a radial shift of particles away from the vortex axis due to...[Show more]
