Optical manipulation of a dielectric particle along polygonal closed-loop geometries within a single water droplet

Abstract We report a new method to optically manipulate a single dielectric particle along closed-loop polygonal trajectories by crossing a suite of all-fiber Bessel-like beams within a single water droplet. Exploiting optical radiation pressure, this method demonstrates the circulation of a single...
