Microfabricated atomic frequency references

April 5, 2005
Author(s)
John Kitching, Svenja A. Knappe, Li-Anne Liew, John Moreland, Hugh Robinson, P Schwindt, V Shah, Leo W. Hollberg
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

Chip-Scale Atomic Frequency References: Fabrication and Performance

John E. Kitching, Svenja A. Knappe, Li-Anne Liew, John Moreland, Hugh Robinson, P Schwindt, V Shah, Vladislav Gerginov, Leo W. Hollberg
The physics package for a chip-scale atomic frequency standard was constructed and tested. The device has a total volume of 9.5 mm 3, dissipates 75 mW of electrical power at an ambient temperature of 45 °C and has a short-term fractional frequency

A chip-scale atomic clock based on 87 Rb with improved frequency stability

Svenja A. Knappe, P Schwindt, V Shah, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John Moreland
We demonstrate a microfabricated atomic clock physics package based on coherent population trapping (CPT) of 87Rb atoms. The package occupies a volume of 12 mm 3 and requires 195 mW of power to operate. Compared to a previous microfabricated clock exciting

C. T-C. Nguyen, John Kitching
This paper describes work towards the use of integrated microelectromechanical systems (MEMS) technology to shrink atomic clocks from their present-day table-top sizes down to only one cubic-centimeter, while retaining exceptional timing stability on the

An Atomic Clock on a Chip

February 1, 2005
Author(s)
John E. Kitching
This article described recent research in the Time and Frequency Division at NIST to develop highly miniaturized atomic frequency references using microfabrication technologies. We discuss the overall physics package design, fabrication of individual

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

Microwave transitions and nonlinear magneto-optical rotation in anti-relaxation-coated cells

January 27, 2005
Author(s)
D Budker, Leo W. Hollberg, Derek F. Kimball, John E. Kitching, S Pustelny, V V. Yashchuk
Using laser optical pumping, widths and frequency shifts are determined for microwave transitions between ground-state hyperfine components of {8s}Rb and d{87}Rb atoms contained in vapor cells with alkane anti-relaxation coatings. The results are compared

John E. Kitching, Svenja A. Knappe, Li-Anne Liew, P Schwindt, V Shah, John M. Moreland, Leo W. Hollberg
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 3, require less than 100 mW of power
