Abstract:
1. A chip-scale atomic clock physics package comprising: a body defining a cavity including a base surface and one or more side walls, wherein the cavity includes a first step surface and a second step surface defined in the one or more side walls; a lid covering an open side of the cavity to enclosed a volume defined by the cavity; a first scaffold mounted to the base surface in the cavity; a laser mounted to the first scaffold; one or more conductive pads on the first step surface; one or more wire bonds extending from the first scaffold to the one or more conductive pads, the one or more wire bonds electrically coupling the laser to the one or more conductive pads; one or more interconnects disposed within the body and extending from the one or more conductive pads on the first step surface to one or more external pads on an exterior surface of the body; one or more spacers defining an aperture therethrough, the one or more spacers having a first surface facing the base surface of the cavity and a second surface facing the lid, wherein the first surface of the one or more spacers is mounted to the second step surface in the cavity; a second scaffold mounted to the first surface of the one or more spacers in the cavity and spanning across the aperture of the one or more spacers; a third scaffold mounted to the second surface of the one or more spacers in the cavity and spanning across the aperture of the one or more spacers; a vapor cell mounted between the second scaffold and the third scaffold and within the aperture defined by the one or more spacers, wherein the vapor cell is mounted to the second scaffold on one side and to the third scaffold on the other side; a photodetector mounted to the third scaffold; and a waveplate, wherein the laser, waveplate, 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 photodetector.
