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