Study of laser-pumped double-resonance clock signals using a microfabricated cell

We present our microwave spectroscopic studies on laser-microwave double-resonance (DR) signals obtained from a micro-fabricated Rb vapor cell. This study focuses on the characteristics and systematic shifts of the ground-state 'clock transition' in Rb-87 ...

Compact microwave cavity for high performance Rubidium frequency standards

Anja Skrivervik, Francesco Merli, Camillo Stefanucci

The design, realization, and characterization of a compact magnetron-type microwave cavity operating with a TE011-like mode are presented. The resonator works at the rubidium hyperfine ground-state frequency (i.e., 6.835 GHz) by accommodating a glass cell ...

New miniaturized microwave cavity for Rubidium atomic clocks

Anja Skrivervik, Jean-François Zürcher, Francesco Merli, Maddalena Violetti

Nowadays there is an increasing need for radically miniaturized and low-power atomic frequency standards, for use in mobile and battery-powered applications. For the miniaturization of double-resonance (DR) Rubidium (Rb-87) atomic clocks, the size reductio ...

Microfabricated rubidium vapour cell with a thick glass core for small-scale atomic clock applications

Nico de Rooij, Danick Briand, Yves Pétremand

This paper presents a new fabrication method to manufacture alkali reference cells having dimensions larger than standard micromachined cells and smaller than glass-blown ones, for use in compact atomic devices such as vapour-cell atomic clocks or magnetom ...

Low-temperature indium hermetic sealing of alkali vapor-cells for chip-scale atomic clocks

Nico de Rooij, Danick Briand, Yves Pétremand

We present a low-temperature indium hermetic bonding technique on wafer level without using flux, active atmosphere or other pretreatment of the indium. Its simplicity and low temperatures allow encapsulation of sensitive MEMS devices. Bonding stronger tha ...

MICROFABRICATION AND PACKAGING OF A RUBIDIUM VAPOR CELL AS A PLASMA LIGHT SOURCE FOR MEMS ATOMIC CLOCKS

Nico de Rooij, Herbert Shea, Yves Pétremand, Vinu Lalgudi Venkatraman

We report on the micro-fabrication and characterization of a chip-scale plasma light source based on a Rubidium (Rb) vapor cell. The Rb plasma light source is intended for use as an integrated optical pump-light source in miniature double-resonance Rb atom ...

3.4 GHz composite thin film bulk acoustic wave resonator for miniaturized atomic clocks

Paul Muralt, Alvaro Artieda

Triple layer SiO2/AlN/SiO2 composite thin film bulk acoustic wave resonators (TFBARs) were studied for applications in atomic clocks. The TFBAR's were tuned to 3.4 GHz, corresponding to half the hyperfine splitting of the ground state of rubidium Rb-87 ato ...

Laser-pumped double-resonance atomic clock using a micro-fabricated Rb cell

Nico de Rooij, Yves Pétremand

We present first results on a laser-pumped, double resonance (DR) Rubidium atomic clock, based on microfabricated Rb vapour cells. The study aims towards a miniature atomic clock [1] based on DR, using a lowpower laser as pump light source and a miniaturiz ...
