Abstract
A device may include an atomic cell with a first wall. A device may include a photonic integrated circuit positioned parallel to the atomic cell first wall, the photonic integrated circuit comprising: a set of three grating emitters mounted on the photonic integrated circuit around a circumference with a spacing of around 120 degrees, wherein each grating emitter is etched to emit free-space beams on to the first wall of the atomic cell at a selected angle, wherein the selected angle in combination with the circumference results in the set of free-space beams intersecting at a location inside the atomic cell.
