Abstract: A photonically multiplexed optical measurement apparatus for performing optical multiplexing includes a laser that produces laser light, an optical switch that receives the laser light from the laser and produces a switched laser light, and a plurality of sensor heads, each sensor head being configured to measure a respective physical property of a plurality of cold atoms disposed in the sensor head. The optical switch optically switches the laser light from the laser to a selected sensor head and subsequently to a different sensor head.

Abstract: A uniaxial counter-propagating monolaser atom trap cools and traps atoms with a single a laser beam and includes: an atom slower that slows atoms to form slowed atoms; an optical diffractor including: a first diffraction grating that receives primary light and produces first reflected light; a second diffraction grating that receives primary light and produces second reflected light; and a third diffraction grating that receives the primary light and produces third reflected light; and a trapping region that forms trap light from the reflected lights and receives slowed atoms to produce trapped atoms from the slowed atoms that interact with the trap light.
