Abstract: An inertial sensing system comprises a first multi-axis atomic inertial sensor, a second multi-axis atomic inertial sensor, and an optical multiplexer optically coupled to the first and second multi-axis atomic inertial sensors. The optical multiplexer is configured to sequentially direct light along different axes of the first and second multi-axis atomic inertial sensors. A plurality of micro-electrical-mechanical systems (MEMS) inertial sensors is in operative communication with the first and second multi-axis atomic inertial sensors. Output signals from the first and second multi-axis atomic inertial sensors aid in correcting errors produced by the MEMS inertial sensors by sequentially updating output signals from the MEMS inertial sensors.

Abstract: A continuously tunable radio frequency (RF) sensor system is provided. The system includes a pump laser system that includes first and second pump lasers, at least one frequency modulator to modulate frequencies of first and second laser light from the pump lasers to first and second select frequencies, a switch system to selectively pass one of the first and second laser light, an amplifier to amplify the passed laser light, a frequency doubler to double the frequency of the amplified laser light to generate pump light. A laser source lock system is in communication with the pump laser system to ensure a frequency of the pump light is referenced to atoms in a vapor cell and provide a probe light. The pump light and probe light are transmitted through the vapor cell. A detector measures the probe light that passed through the vapor cell.

Abstract: A device includes a substrate and nanoscale fin formed from a first material, a RF emitter that emits energy in a range of radio frequencies, and a waveguide formed from a second material. The device further includes a bichromatic directional coupler configured to couple pump and probe laser light into the waveguide. The waveguide is positioned proximate to the nanoscale fin along a coupling length such that the pump laser light propagating within the waveguide is coupled into the nanoscale fin from evanescent wave overlap along the coupling length. The pump laser light causes the first material to absorb the probe laser light when energy emitted by the RF emitter is at one or more frequencies dependent on a magnetic field. The device further includes a processor configured to determine a magnetic field strength of the magnetic field based on an identification of the one or more frequencies.

Abstract: A chip scale atomic clock (CSAC) includes a temperature stabilized physics system and a temperature stabilized electronics circuitry electrically coupled to the temperature stabilized physics system. Atomic clocks utilize an optical signal having a frequency component. The temperature stabilization increases frequency stability. The temperature stabilized physics system includes a vapor cell and a magnetic field coil, and is enclosed in a magnetic shield. When an ambient temperature of a chip scale atomic clock increases, fluid is extended away, due to thermal expansion, from at least one reservoir towards or away from a thermally isolated subsystem in at least one of the temperature stabilized electronics circuitry and the temperature stabilized physics system.

Abstract: Waveguide includes fork with first and second bifurcated ends coupled to loop section and separated by angle determined based on velocities of portions of quantum mechanical wavefunction of atoms traveling above waveguide. Waveguide propagates blue-detuned laser having first evanescent field that repels atoms away from waveguide and red-detuned laser having second evanescent field that attracts atoms toward waveguide, together creating potential minimum/well. Laser cooling atoms, causing atoms positioned in potential minimum/well to move toward first fork section following potential minimum/well. Atomic state initialization section initializes atomic states of atoms to known ground-state configuration. Beam splitter section splits quantum mechanical waveform of each atom above surface of diverging waveguide into first portion at first velocity that travels into first end of first fork section into first loop section and second portion at second velocity that travels into second end of first fork section into first loop section.
