21. Chip-scale atomic magnetometer
Published: 12/27/2004
Authors: P Schwindt, Svenja A Knappe, V Shah, Leo W. Hollberg, John E Kitching, Li-Anne Liew, John Moreland
Abstract: Using the techniques of micro-electro-mechanical systems (MEMS), we have constructed a small, low-power magnetic sensor based on alkali atoms. By measuring the energy shift of the atoms' magnetic moment due to a magnetic field via a coherent populati ...

22. Microfabricated Atomic Clocks at NIST
Published: 12/7/2004
Authors: Svenja A Knappe, P Schwindt, Vladislav Gerginov, V Shah, Leo W. Hollberg, John E Kitching, Li-Anne Liew, John Moreland
Abstract: In this paper we present the latest progress in the development, fabrication, and characterization of a microfabricated atomic frequency reference at NIST. With volumes below 10 mm3 the physics packages contain the complete integrated assembly for pr ...

23. Chip-Scale Atomic Magnetometers
Published: 12/1/2004
Authors: P Schwindt, Svenja A Knappe, V Shah, Leo W. Hollberg, John E Kitching, Li-Anne Liew, John M Moreland
Abstract: Using the techniques of micro-electro-mechanical systems, we have constructed a small, low-power magnetic sensor based on alkali atoms. We use a coherent population trapping resonance to probe the interaction of the atoms' magnetic moment with a mag ...

24. Power dissipation in a vertically integrated chip-scale atomic clock
Published: 8/24/2004
Authors: John E Kitching, Svenja A Knappe, Li-Anne Liew, P Schwindt, V Shah, John Moreland, Leo W. Hollberg
Abstract: The physics package of a vertically-integrated chip-scale atomic clock based on Cs has recently been demonstrated at NIST. This device requires 69 mW of electrical power to maintain the vapor cell 34 K above the temperature of the baseplate. The phys ...

25. Microfabricated Atomic Frequency References
Published: 8/23/2004
Authors: Svenja A Knappe, P Schwindt, V Shah, Leo W. Hollberg, John E Kitching, Li-Anne Liew, John Moreland
Abstract: We report on the fabrication of a physics package for a chip-scale atomic clock with a volume of 9.5 mm^3, consuming 75 m W of power. The design is described in detail and is strongly motivated by the goal of wafer-level fabrication and assembly. A f ...

26. Microfabricated Atomic Frequency References
Published: 8/1/2004
Authors: Svenja A Knappe, P Schwindt, V Shah, Leo W. Hollberg, John E Kitching, Li-Anne Liew, John M Moreland
Abstract: We describe a design for a microfabricated atomic frequency reference with a volume of several cubic millimetres and a power dissipation in the range ot tens of milliwatts. It is anticipated that this frequency reference will be capable of achieving ...

27. Microfabricated alkali atom vapor cells
Published: 4/5/2004
Authors: Li-Anne Liew, Svenja A Knappe, John M Moreland, Hugh Robinson, David C. Larbalestier, John E Kitching
Abstract: We describe the fabrication of chip-sized alkali atom vapor cells using silicon micromachining and anodic bonding technology. Such cells may find use in highly miniaturized atomic frequency references or magnetometers. The cells consist of cavities e ...
