Abstract

There has been recent interest in using room-temperature atomic vapors and beams to achieve compact technological solutions, such as chip-scale magnetometry and atomic clocks. Here we integrate a chip-scale rubidium beam source with a high finesse optical cavity to create an atomic cavity-QED system.

A chip-scale atomic beam source for non-classical light

B. M. Larsen, Hensley, Hagan, Gabriela D. Martinez +4 more

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. Here, we show that a chip-scale rubidium beam source can be integrated with a high finesse cavity-QED system to generate non-classical light. By demonstrating the compatibility of these two technologies, we open a new path for distributed sources of non-classical light and set the stage for using cavity-QED to enhance the performance of chip-scale magnetometers and atomic clocks.

A chip-scale atomic beam for nonclassical light

B. M. Larsen, Hagan Hensley, Gabriela D. Martinez +4 more

Nonclassical light is a critical resource for a broad range of quantum technologies and fundamental science. However, leading platforms such as laser-cooled atoms and solid-state systems both present substantial challenges to scalability due to complexity and spectral drift. Here, we demonstrate a hybrid approach using a chip-scale rubidium beam coupled to a high-finesse cavity-quantum electrodynamics (QED) system. Specifically, we generate nonclassical light and observe optical nonlinearities at the few photon level. This is achieved without degradation of the cavity-QED system. By demonstrating the compatibility of these two technologies, we open a path for distributed sources of nonclassical light and set the stage for using cavity-QED to enhance the performance of chip-scale magnetometers and atomic clocks.
