11. Chip-Scale Atomic Clocks at NIST
Published: 8/7/2005
Authors: John E Kitching, Svenja A Knappe, Li-Anne Liew, John Moreland, Hugh Robinson, P Schwindt, V Shah, Vladislav Gerginov, Leo W. Hollberg
Abstract: We describe recent efforts to develop microfabricated atomic frequency references capable of supporting a wide variety of commercial and military systems such as global positioning and wireless communication. These devices are anticipated to eventual ...

12. Microfabricated Atomic Frequency References
Published: 8/1/2005
Authors: John E Kitching, Svenja A Knappe, Li-Anne Liew, John M Moreland, Peter D. Schwindt, V Shah, V Gerginov, Leo W. Hollberg
Abstract: Using microfabrication processes, we have been able to construct physics packages for vapour cell atomic frequency references 100x smaller than previously existing versions, with a corresponding reduction in power consumption. In addition, the device ...

14. Microfabricated atomic frequency references
Published: 4/5/2005
Authors: John E Kitching, Svenja A Knappe, Li-Anne Liew, John Moreland, Hugh Robinson, P Schwindt, V Shah, Leo W. Hollberg
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 ...

15. Chip-Scale Atomic Frequency References: Fabrication and Performance
Published: 3/21/2005
Authors: John E Kitching, Svenja A Knappe, Li-Anne Liew, John Moreland, Hugh Robinson, P Schwindt, V Shah, Vladislav Gerginov, Leo W. Hollberg
Abstract: The physics package for a chip-scale atomic frequency standard was constructed and tested. The device has a total volume of 9.5 mm^u3^, dissipates 75 mW of electrical power at an ambient temperature of 45 {degree}C and has a short-term fractional fre ...

16. A chip-scale atomic clock based on ^u87^Rb with improved frequency stability
Published: 2/21/2005
Authors: Svenja A Knappe, P Schwindt, V Shah, Leo W. Hollberg, John E Kitching, Li-Anne Liew, John Moreland
Abstract: We demonstrate a microfabricated atomic clock physics package based on coherent population trapping (CPT) of ^u87^Rb atoms. The package occupies a volume of 12 mm^u3^ and requires 195 mW of power to operate. Compared to a previous microfabricated clo ...

17. Microfabricated Atomic Clocks
Published: 1/30/2005
Authors: John E Kitching, Svenja A Knappe, Li-Anne Liew, P Schwindt, V Shah, John Moreland, Leo W. Hollberg
Abstract: We summarize the development of microfabricated atomic frequency references at NIST. The physics packages of these devices have volumes near 10 mm3, power dissipation below 150 mW and can potentially achieve a fractional frequency instability in the ...

20. Microfabricated Atomic Clocks
Published: 1/1/2005
Authors: John E Kitching, Svenja A Knappe, Li-Anne Liew, P Schwindt, V Shah, John M Moreland, Leo W. Hollberg
Abstract: We describe recent progress at NIST in the development of compact, low-power atomic frequency references based on microfabrication processes. The physics packages of these frequency references have a volume near 10 cm^u3^, require less than 100 mW of ...
