Generation of Airy vortex beam arrays using computer-generated holography

We report on the generation of diverse arrays of Airy vortex beams (AiVBs) with normal or deformed structures by employing computer-generated holography. The intensity distributions and evolution of the arrays containing four AiVBs with different topological charges are theoretically and experimentally studied. The generated AiVBs are converged due to the self-bending characteristic independent of the sign and topological charges of the AiVBs. The experimental and numerical results agree well with each other. These novel arrays are expected to be used for multiple capture or manipulation of particles at the same time but at different positions, providing powerful theoretical and experimental bases for improving the efficiency of optical manipulation.
