1. A chip-scale atomic clock, comprising:

  • a physics package;

    a laser die located in a first thermal zone of the physics package;

    a quarter wave plate mounted in the physics package and in optical communication with the laser die;

    a vapor cell mounted in the physics package and in optical communication with the quarter wave plate, the vapor cell located in a second thermal zone that is independent from the first thermal zone; and

    an optical detector mounted in the physics package and in optical communication with the vapor cell;

    wherein the first thermal zone provides a first operation temperature at a first stability point associated with the laser die, and the second thermal zone provides a second operation temperature at a second stability point associated with the vapor cell.
