Abstract

We present measurements regarding the long-term stability of chip-scale atomic clock (CSAC) physics packages. The tight requirements for the temperature stability of vapor cell and laser in these packages currently limit their frequency stability after 100-1000 seconds. Even with advanced MEMS packaging techniques such as vacuum sealing or thermal insulation, it seems difficult to maintain the required stabilities in small, low-power setups over a large range of ambient temperatures. In order to make CSACs useful devices for portable applications in the area of navigation and communication this problem needs to be addressed.
