Abstract
Systems and methods for an integrated photonics quantum vector magnetometer are provided herein. In certain embodiments, a device includes a substrate; a radio frequency emitter that emits energy in a range of radio frequencies; and a waveguide layer formed on the substrate. The waveguide layer includes a first waveguide of a first material, wherein a probe laser is propagating within the first waveguide; and a second waveguide, wherein the second waveguide is positioned proximate to the first waveguide along a coupling length such that a pump laser propagating within the second waveguide is coupled into the first waveguide along the coupling length, wherein the pump laser causes the first material to absorb the probe laser at one or more frequencies in the range of frequencies. Moreover, the device includes a processing device that calculates a magnetic field strength based on an identification of the one or more frequencies.
