论文摘要
使用全dielectric nano-antennae调整近场的近场提供了一种有前途的捕获原子的方法,这可以实现强大的单原子/光子耦合。在这里,我们报告了光学诱捕概念的仿真结果,其中硅纳米 - 安妮娜在芯片尺度构型中产生了原子的诱捕潜力。使用反向传输的入射场,双章从原子剖以D线中解息,我们从数值上研究了光电位对纳米 - 安特纳几何几何形状的依赖性。我们通过使用环形纳米 - 安妮娜(Nano-Antenna)调整波导的渐态田地来量身定制近场电势景观,这种构型可捕获超低CS原子。
Tuning the near-field using all-dielectric nano-antennae offers a promising approach for trapping atoms, which could enable strong single-atom/photon coupling. Here we report the simulation results of an optical trapping concept, in which a silicon nano-antenna produces a trapping potential for atoms in a chip-scale configuration. Using counter-propagating incident fields, bichromatically detuned from the atomic cesium D-lines, we numerically investigate the dependence of the optical potential on the nano-antenna geometry. We tailor the near-field potential landscape by tuning the evanescent field of the waveguide using a toroidal nano-antenna, a configuration that enables trapping of ultracold Cs atoms.
