Tractor Beam Conveyor Belt for Tiny Particles

LV13165 - A tractor beam is a traveling wave that can transport illuminated material along its length back to its source.  Here, we demonstrate one-sided optical conveyors that act as tractor beams without requiring outside assistance. The same technique we use to project a single optical conveyor also can project arrays of optical conveyors each with independently controlled transport properties.
