We propose to use dielectric metasurface as a novel platform to generate dipole trap arrays with high quality and efficiency. According to the specific design parameters of the dipole trap array, the modulation phase and the focusing phase are calculated respectively. Building upon this, we design a metasurface device consisting of cylindrical TiO 2 -based integrated-resonant unit-cells by combining the modulating phase with the focusing phase. In addition, by finely adjusting the position of the nanopillar, a good match between the theoretical phase and the transmission phase of the nanopillar can be achieved to reduce the aberration introduced by the metasurface device. We conducted simulation experiments to demonstrate several configurations of dipole trap arrays. The results indicate that the obtained dipole trap arrays are precisely positioned and have uniform intensity distribution. The spacing and quantity of the traps obtained through this method can be controlled, providing a versatile and scalable system for neutral single-atom quantum information processing and quantum simulation. • By finely tuning the nanopillar position on the metasurface, we achieve a precise match between theoretical and transmission phases. • Combining modulation and focusing phases, our designed metasurface device replaces the function of both the SLM and strong focusing systems. • We use dielectric metasurface as a novel platform to generate dipole trap arrays for single-atom system with high quality and efficiency.
