A chip-scale atomic beam clock



Gabriela Martinez, Chao Li, Alexander Staron, John Kitching, Chandra Raman, William McGehee


We demonstrate a passively pumped, chip-scale atomic beam clock fabricated using a stack of silicon and glass wafers. The device could additionally serve as a platform for compact atom interferometers and other future quantum sensors.
