ABSTRACT:
An optical-physics package used in an atomic frequency standard is miniaturized and the performance thereof improved. The optical-physics package includes a microwave cavity in which is positioned a filter cell and an absorption cell, preferably located in close physical proximity to one another. The microwave cavity may double as an oven, and is preferably designed to operate in the TE111 mode with "E" probe microwave coupling. Dielectric loading is provided by the filter cell and absorption cell to reduce the internal dimensions of the microwave cavity.
