摘要

我们提出超表面全息图作为一种新的平台来产生高质量、高效率和热稳定性的冷原子光学阱阵列。我们开发了设计和制造方法来创建基于二氧化钛的介电,纯相位超表面全息图。我们通过实验展示了各种几何形状的光学陷阱阵列,包括周期和非周期配置,尺寸范围从1D到3D,多达数百个陷阱点。我们从定位精度、产生陷阱的尺寸和强度均匀性以及介电超表面的功率处理能力等方面对全息超表面的性能进行了表征。我们提出的平台在量子多体物理、量子模拟和计算任务的基础研究方面具有巨大的潜力。紧凑的外形因素、无源特性、良好的功率处理能力以及生成高质量、大规模阵列的可扩展性也使超表面平台特别适合实现基于冷原子的现场可部署设备和系统。

Metasurface holographic optical traps for ultracold atoms

We propose metasurface holograms as a novel platform to generate optical trap arrays for cold atoms with high quality, efficiency, and thermal stability. We developed design and fabrication methods to create dielectric, phase-only metasurface holograms based on titanium dioxide. We experimentally demonstrated optical trap arrays of various geometries, including periodic and aperiodic configurations with dimensions ranging from 1D to 3D and up to a few hundred trap sites. We characterized the performance of the holographic metasurfaces in terms of the positioning accuracy, size and intensity uniformity of the generated traps, and power handling capability of the dielectric metasurfaces. Our proposed platform has great potential for enabling fundamental studies of quantum many-body physics, and quantum simulation and computation tasks. The compact form factor, passive nature, good power handling capability, and scalability of generating high-quality, large-scale arrays also make the metasurface platform uniquely suitable for realizing field-deployable devices and systems based on cold atoms.
