Abstract

We describe recent efforts to develop microfabricated atomic frequency references capable of supporting a wide variety of commercial and military systems such as global positioning and wireless communication. These devices are anticipated to eventually have a volume of 1 cm3, dissipate less than 30 mW of electrical power and maintain a fractional frequency stability better than 10-11 over one hour. Because of the small size and low power requirements, these devices will enable atomic-level timekeeping in portable, battery-powered units.
