A CPT-based Cs cell self-sustained microwave oscillator

Résumé

We report the implementation of a CPT-based Cs cell microwave feedback oscillator. Here, a high-Q atomic resonance initiated through CPT in a buffer-gas filled Cs vapor cell is detected with a fast photodiode, amplified and sustained in a loop oscillator configuration, comparable to those of optoelectronic oscillators (OEOs). The Cs cell oscillator currently demonstrates at 9.192 GHz a phase noise of –24, –82 and –112
