Abstract
The cost and size of an atomic magnetometer are reduced by attaching together a first die which integrates together a vapor cell, top and side photo detectors, and processing electronics, a second die which integrates together an optics package and a heater for the vapor cell, and a third die which integrates together a VCSEL, a heater for the VCSEL, and control electronics.
