Chip-scale atomic magnetometer

December 27, 2004

Author(s)

P Schwindt, Svenja A. Knappe, V Shah, Leo W. Hollberg, John Kitching, Li-Anne Liew, John Moreland

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 population

Microfabricated Atomic Clocks at NIST

December 7, 2004

Author(s)

Svenja A. Knappe, P Schwindt, Vladislav Gerginov, V Shah, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John Moreland

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 probing

Chip-Scale Atomic Magnetometers

Author(s)

P Schwindt, Svenja A. Knappe, V Shah, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John M. Moreland

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 magnetic

High-contrast dark resonances in s+ -s- optical field

October 1, 2004

Author(s)

S. Kargapoltsev, John Kitching, Leo W. Hollberg, A. V. Taichenachev, V L. Velichanski, V. I. Yudin

For application to atomics clocks, it is important to have large amplitude and small width of the CPT resonance. In this paper, we show that the contrast and amplitude of the dark resonance can be significantly increased in a miniature buffer gas cell by

Power dissipation in a vertically integrated chip-scale atomic clock

August 24, 2004

Author(s)

John Kitching, Svenja A. Knappe, Li-Anne Liew, P Schwindt, V Shah, John Moreland, Leo W. Hollberg

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 physics

Microfabricated Atomic Frequency References

August 23, 2004

Author(s)

Svenja A. Knappe, P Schwindt, V Shah, Leo W. Hollberg, John Kitching, Li-Anne Liew, John Moreland

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

Microfabricated Atomic Frequency References

August 1, 2004

Author(s)

Svenja A. Knappe, P Schwindt, V Shah, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John M. Moreland

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 a

Microfabricated alkali atom vapor cells

Author(s)

Li-Anne Liew, Svenja A. Knappe, John M. Moreland, Hugh Robinson, David C. Larbalestier, John Kitching

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 etched

Micromachined Alkali Atom Vapor Cells for Chip-Scale Atomic Clocks

Li-Anne Liew, Svenja A. Knappe, John M. Moreland, Hugh Robinson, Leo W. Hollberg, John Kitching

This paper describes the fabrication of chip-sized alkali atom vapor cells, for use in highly miniaturized atomic frequency references, using silicon micromachining and anodic bonding technology. The cells consist of silicon cavities with internal volume
