MEMS Technology

The components of an atomic magnetometer consist of a cell containing an alkali element such as cesium, a source of light of the proper wavelength, and a photocell to detect the intensity of the light. Advances in MEMS fabrication have led to the ability to inexpensively create 1mm cubic volumes of cesium gas. Laser diode technology was used to create devices efficiently emitting light of the proper wavelength. MEMS packaging techniques can bring these components into the required arrangement at low cost in high volume.
