Abstract: A package for a chip scale atomic clock or magnetometer is disclosed. The package includes a vapor cell using an alkali metal vapor, first and second photodetectors, and a laser operable at a frequency that excites an electron transition in the alkali metal vapor. The laser is positioned to provide an optical signal directed through the vapor cell and towards the first photodetector. The package further contains a polarizing beam splitter, the polarizing beam splitter positioned between the vapor cell and the first photodetector to receive the optical signal and to split the optical signal into a first signal directed toward the first photodetector and a second signal directed toward the second photodetector, the first signal being orthogonal to the second signal.

Abstract: One embodiment of an integrated circuit device includes a semiconductor substrate with a top surface, a bottom surface opposite said top surface and an intermediate portion positioned between the top and bottom surfaces. The device also includes interior substrate surfaces defined by at least one void extending from the bottom surface to the intermediate portion.
