Simultaneous manipulation of microparticles in multiple planes with the Thue–Morse zone plate beam

Shubo Cheng, Tian Xia, Mengsi Liu and Shaohua Tao

We demonstrate optical manipulation with an optical beam generated by a Thue–Morse zone plate (TMZP) in this paper. The results show that the generated TMZP beam can simultaneously manipulate microparticles positioned in multiple focal planes of the beam, owing to the self-reconstruction property and the symmetry foci with the same intensity along the optical axis. The TMZP beam will be promising in the three-dimensional optical tweezers.
