Résumé
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 <sup>87</sup>Rb (
<i>F</i><sub>g</sub> = 1, <i>m</i><sub>F</sub> = 0⟩ →
<i>F</i><sub>g</sub> = 2, <i>m</i><sub>F</sub> = 0⟩) used in Rb atomic clocks, and represents a first step toward a miniature atomic clock based on the DR scheme. A short-term clock instability below 2 × 10<sup>11</sup><i>τ</i><sup>−1/2</sup> is demonstrated, staying below 10<sup>−11</sup> up to <i>τ</i>= 10<sup>4</sup> s.
