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: 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.

An annular cavity is formed in a first surface of a substrate, the annular cavity defining an anchor post located in a central portion of the annular cavity. A bubble layer is formed over the first surface of the substrate and over the annular cavity. The substrate and the bubble layer are heated to form a hemitoroidal bubble in the bubble layer over the annular cavity. A sacrificial layer is deposited over the hemitoroidal bubble of the bubble layer and an aperture is formed in the sacrificial layer, the aperture disposed over the anchor post in the annular cavity. A resonator layer is deposited over the sacrificial layer and the sacrificial layer between the bubble layer and the resonator layer is removed.

Abstract: An atomic inertial interferometer comprises a laser that emits a CW beam; a modulator that modulates the CW beam; a filter and delay mechanism that receives the modulated beam, and includes a first pathway and a second pathway longer than the first pathway; a comb generator that receives the modulated beam, and produces a frequency comb; and a comb drive coupled to the comb generator to generate a multiple of a comb repetition rate, the comb drive including a HF source coupled to a bandpass filter. A vacuum cell holds a sample of cold atoms. The frequency comb counter-propagates with respect to the modulated beam to provide velocity slicing of the cold atoms such that a given temperature distribution of the cold atoms is sliced into a plurality of narrow temperature distributions that are probed individually and in parallel, to extract an interference signal from the narrow temperature distributions.

Abstract: A thermal metamaterial device comprises at least one MEMS thermal switch, including a substrate layer including a first material having a first thermal conductivity, and a thermal bus over a first portion of the substrate layer. The thermal bus includes a second material having a second thermal conductivity higher than the first thermal conductivity. An insulator layer is over a second portion of the substrate layer and includes a third material that is different from the first and second materials. A thermal pad is supported by a first portion of the insulator layer, the thermal pad including the second material and having an overhang portion located over a portion of the thermal bus. When a voltage is applied to the thermal pad, an electrostatic interaction occurs to cause a deflection of the overhang portion toward the thermal bus, thereby providing thermal conductivity between the thermal pad and the thermal bus.
