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 clock is provided. An output of a tunable LO is coupled to a user output of the atomic clock. A charge pump adjusts the tunable LO with a LO tuning voltage. A follower circuit sets an output frequency of the atomic clock to a frequency of an external reference signal coupled to an external reference input. An atom referenced circuit sets the output frequency of the atomic clock to a frequency based on stored operating settings. A controller stores then current operating settings generated based on a then current external reference signal coupled to the external reference input. The controller is further configured to apply the stored then current operating settings to the atom referenced circuit when the then current external reference signal is removed from the external reference input to maintain the output frequency of the atomic clock at the output frequency set by the follower circuit.

Abstract: A photonics device comprises a waveguide platform including a substrate layer, a cladding layer over the substrate layer, and a waveguide layer embedded in the cladding layer. The waveguide layer includes a waveguide ring resonator, and a bus waveguide in optical communication with the waveguide ring resonator. The waveguide ring resonator is configured to generate a stimulated Brillouin scattering (SBS) beam when a pump laser beam is optically coupled into the waveguide ring resonator from the bus waveguide. The waveguide ring resonator has a radius and corresponding round-trip path length such that a free-spectral range (FSR) of the waveguide ring resonator is misaligned with respect to a SBS gain peak of the SBS beam, such that an SBS gain coefficient has a magnitude to produce a substantially reduced linewidth of the SBS beam.

Abstract: An optical device comprises a substrate layer having an upper surface, and a waveguide layer over the upper surface of the substrate layer. The waveguide layer comprises an input waveguide defined by a first waveguide portion having a first refractive index; an input slab defined by the first waveguide portion, the input slab adjoined with the input waveguide; and a microlens array defined by a second waveguide portion having a second refractive index that is different from the first refractive index. The microlens array is in optical communication with the input waveguide through the input slab. The microlens array is configured to receive a diverging planar light beam from the input slab along a direction of propagation. The microlens array is configured to control a far-field emission of the light beam such that an emission profile of the light beam exhibits a substantially uniform intensity.

Abstract: A multilayer waveguide coupler comprising a first grating and a second grating is provided. Each first copropagating waveguide of the first grating has a first periodically modulated width. Each second copropagating waveguide of the second grating has a second periodically modulated width. The second grating is positioned so that a phase offset is present between the first periodically modulated width of the first copropagating waveguides and the second periodically modulated width of the second copropagating waveguides. The grating spaced distance and phase offset are selected so that light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the first direction interferes constructively to form the first light beam and light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the second direction interferes destructively.

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 methods for direct measurement of imbalanced optical paths using entangled photons are provided. A system includes an optical source for generating a pair of simultaneously produced photons. The system also includes first and second emitter/receivers that emit first and second photons in the pair of simultaneously produced photons towards a first and second remote reflector and receives the reflected first and second photons along first and second optical paths. Further, the system includes a mode combiner for combining the reflected first and second photons into first and second output ports. Moreover, the system includes photodetectors that detect photons from the first and second output ports. Also, the system includes a processor that measures a difference in time delay between the first and second optical paths based on a time difference of arrival of signals from the photodetectors.
