    Abstract: A sensor system comprises a laser source that emits a pump beam at a first wavelength and a probe beam at a second wavelength, and an optical means for receiving the pump and probe beams. The optical means is operative to generate a plurality of light beams, each having a different frequency, from the pump and probe beams. One or more cells receive the light beams from the optical means and allow passage of the light beams therethrough, with the cells containing alkali atoms. A dichroic filter is configured to receive the light beams from the cells. The dichroic filter separates pump beam light and probe beam light from the light beams. A detector array receives the probe beam light from the dichroic filter. The detector array includes a two-dimensional array of photosensors that map out transmission of respective light beams corresponding to the probe beam light through the cells.

    Abstract: Systems and embodiments for an integrated photonics tensor magnetometer are described herein. In certain embodiments, a system includes a plurality of magnetometers. The system also includes a laser carrier wafer coupled to each of the plurality of magnetometers that commonly distributes one or more lasers to each of the magnetometers in the plurality of magnetometers. Additionally, the system includes a plurality of photodetectors that detect light emitted from the laser carrier wafer and the plurality of magnetometers. Further, the system includes one or more processors that execute computer-executable instructions that cause the processor to monitor and control operation of the one or more lasers and calculate a magnetic field gradient based on the detected light from the magnetometers.

    Abstract: Systems and methods for eliminating multi-path errors from atomic inertial sensors are provided. In certain embodiments, a system for performing atom interferometry includes a vacuum cell containing multiple atoms and a first plurality of lasers configured to trap the atoms within the vacuum cell. The system further includes a second plurality of lasers configured to impart momentum to the atoms and direct the atoms down multiple paths, wherein a primary path in the multiple paths has a first and second component that converge at a converging point, wherein a diverging part of the primary path in which the first and second components are diverging is asymmetrical with respect to a converging part of the primary path in which the first and second components are converging, such that only the first and second components converge at the converging point wherein other paths do not converge at the converging point.

    Abstract: An atomic interferometric accelerometer comprises a laser that emits a pulsed beam at a first frequency, an electro-optic modulator that receives the beam, and a vacuum cell in communication with the electro-optic modulator. The electro-optic modulator outputs a first optical signal corresponding to the beam at the first frequency and a second optical signal having a second frequency different from the first frequency. The vacuum cell has a chamber for laser cooled atoms. The vacuum cell receives the optical signals such that they propagate in a direction that passes through the atoms. A piezo mirror retro-reflects the optical signals back through the vacuum cell in a counter-propagating direction. The piezo mirror is driven with substantially constant velocity during a beam pulse, thereby imparting a Doppler shift to the retro-reflected optical signals to create two non-symmetric counter-propagating lightwave pairs. One of the lightwave pairs supports interferometry while the other is non-resonant.

    Abstract: In some examples, a controller is configured to generate a key based on a physics-based output of a component. The controller may, for example, use the key to authenticate communication between at least two nodes, to encrypt data, or to decrypt data. In some examples, the component includes one or more subcomponents, each subcomponent including a cell filled with a gas, a light source configured to transmit a light through the gas cell, and a photodetector configured to sense light transmitted through the gas cell. The photodetector of each subcomponent is configured to generate an electrical signal that changes as a function of one or more properties of the light sourced by the light source, transmitted through the gas cell. The output of the component can is based on the signals generate by the one or more photodetectors.
