Researchers Proposed an Active Optical Microclock Based on the Lattice-trapped Atoms

A joint research team from the National Time Service Center of the Chinese Academy of Sciences (NTSC) and the University of Exeter proposed an active optical microclock based on the lattice-trapped atoms evanescently interacting with a whispering-gallery-mode (WGM) microcavity. The numerical simulation illustrates that the microclock's frequency stability potentially reaches 1.5×10-14 at 1 s of averaging.
