A micro-fabricated atomic clock structure is thermally insulated so that the atomic clock structure can operate with very little power in an environment where the external temperature can drop to &#x2212;40&#xb0; C., while at the same time maintaining the temperature required for the proper operation of the VCSEL and the gas within the vapor cell.

The spikes in current and voltage that result from the failure of a galvanic dielectric layer are safely contained by a galvanic isolation fuse that pops and forms and open circuit between a high-voltage die and a low-voltage die in response to the failure of the galvanic dielectric layer.
