We present a coherent-population-trapping-based scheme to attain subnanoscale resolution for microscopy. We use three-level atoms coupled to an amplitude modulated probe field and a spatially dependent (standing-wave or Laguerre-Gaussian) coupling field. The probe field modulation allows us to tap into the steep dispersion normally associated with electromagnetically induced transparency and offers subnanometer resolution using optical fields.
我们提出了一种基于相干布居囚禁的方案，以实现亚纳米级分辨率的显微镜。我们使用耦合到振幅调制探针场和空间相关（驻波或拉盖尔-高斯）耦合场的三能级原子。探针场调制使我们能够利用通常与电磁感应透明相关的陡峭色散，并使用光学场实现亚纳米分辨率。
