We have proposed a novel concept, “optical vortex comb,” that enables precise spatiotemporal phase control by combining optical combs with optical vortices. In the present talk, an optical ring lattice, which is generated by a “dual-optical vortex comb,” is applied for optical tweezers. Through an experiment of optical manipulation for polystyrene beads, we demonstrate arbitrary rotational manipulation via the frequency control of optical combs.
