Abstract
In an example, a chip-scale atomic clock physics package is provided. This chip-scale atomic clock physics package includes a body defining a cavity, and a first scaffold mounted in the cavity. A laser is mounted on the first surface of the first scaffold. A second scaffold is also mounted in the cavity. The second scaffold is disposed such that the first surface of the second scaffold is facing the first scaffold. A first photodetector is mounted on the first surface of the second scaffold. A vapor cell is mounted on the first surface of the second scaffold. A waveplate is also included, wherein the laser, waveplate, first photodetector, and vapor cell are disposed such that a beam from the laser can propagate through the waveplate and the vapor cell and be detected by the first photodetector. A lid is also included for covering the cavity.
