  • Abstract
    We report on the fabrication of a physics package for a chip-scale atomic clock with a volume of 9.5 mm3, consuming 75 mW of power. The design is described in detail and is strongly motivated by the goal of wafer-level fabrication and assembly. A fractional frequency instability of 2.4 × 10-10 at one second of integration is demonstrated; the long-term drift is -2 × 10-8/day. We discuss the performance of the clock at short and long integration times as well as its power consumption, and suggest possible improvements.
