Abstract
Systems and embodiments for an integrated photonics tensor magnetometer are described herein. In certain embodiments, a system includes a plurality of magnetometers. The system also includes a laser carrier wafer coupled to each of the plurality of magnetometers that commonly distributes one or more lasers to each of the magnetometers in the plurality of magnetometers. Additionally, the system includes a plurality of photodetectors that detect light emitted from the laser carrier wafer and the plurality of magnetometers. Further, the system includes one or more processors that execute computer-executable instructions that cause the processor to monitor and control operation of the one or more lasers and calculate a magnetic field gradient based on the detected light from the magnetometers.
