A chip-scale atomic beam for non-classical light

Room temperature thermal atoms have proven to be a powerful resource for magnetometry, electrometry, atom-entanglement generation, and robust atomic clocks. Recent efforts have sought to realize compact and highly manufacturable atomic vapors and atomic beams for chip-scale magnetometry and atomic clocks. We show progress towards integrating a high finesse optical cavity and rubidium beam source into a single package to create a chip-scale cavity QED platform. The compatibility of these two technologies will set the stage for using cavity-QED to enhance the performance of chip-scale magnetometers and atomic clocks and open a new path for distributed sources of non-classical light.
