Systems and methods for an integrated optical atomic sensor

An optical atomic sensor system, the sensor comprising:

• optical atomic sensor;
• at least one laser light source coupled to the optical atomic sensor;
• and
• a control circuit coupled to the optical atomic sensor and the at least one laser light source;
• wherein the optical atomic sensor comprises:
• a first photonic integrated circuit;
• a second photonic integrated circuit;
• an atom trapping chamber positioned between and bonded to the first photonic integrated circuit and the second photonic integrated circuits with the first photonic integrated circuit and the second photonic integrated circuits aligned parallel to each other;
• and
• a sample of atomic vapor sealed within the atom trapping chamber;
• wherein the first photonic integrated circuit and second photonic integrated circuit each comprise:
• a plurality of grating emitters fabricated into respective surfaces of the first and second photonic integrated circuits;
• and
• a system of waveguides coupled to that at least one laser light source and configured to couple laser light to the plurality of grating emitters;
• wherein at least one set of the plurality of grating emitters on each of the first photonic integrated circuit and the second photonic integrated circuit are arranged to launch laser light beams into the atom trapping chamber in a pattern structured to cool the atomic vapor and produce at least one atom trap inside the chamber;
• and
• wherein the plurality of grating emitters on both of the first photonic integrated circuit and the second photonic integrated circuit further include at least one grating emitter configured to emit a laser light probe into the atomic vapor.
