Enhancing near-field optical tweezers by spin-to-orbital angular momentum conversion

Near-field patterns of light provide a way to optically trap, deliver, and sort single nanoscopic particles in a wide variety of applications in nanophotonics, microbiology, and nanotechnology. Using rigorous electromagnetic theory, we investigate the forces and trapping performance of near-field op...
