2. 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 ...

3. A chip-scale atomic magnetometer with improved sensitivity using the M^dx^ technique
Published: 2/26/2007
Authors: P Schwindt, Brad Lindseth, Svenja A Knappe, V Shah, John E Kitching, Li-Anne Liew
Abstract: We discuss the fabrication and performance of a miniature optically pumped atomic magnetometer constructed using microfabricated components. This device measures the spin precession frequency of an alkali atom to determine the magnetic field using th ...

6. Atomic vapor cells for miniature frequency references
Published: 5/8/2003
Authors: Svenja A Knappe, V. Velichansky, Hugh Robinson, Li-Anne Liew, John M Moreland, John E Kitching, Leo W. Hollberg
Abstract: We report on the fabrication of millimeter-sized vapor cells and their performance on atomic clocks based on coherent population trapping (CPT). We discuss two fabrication techniques, the first one based on hollow-core pyrex fibers, fused with a CO^d ...
