Coupled electromechanical resonators that can be independently driven/detected and easily integrated with external circuits are essential for exploring mechanical modes based signal processing. Here, we present a room temperature phonon-cavity electr

Silicon nitride (SiN) mechanical resonators with high quality mechanical properties are attractive for fundamental research and applications. However, it is challenging to maintain these mechanical properties while achieving strong coupling to an ele

Bulk Acoustic Wave Resonators (BAW) have been studied in Time and Frequency domain for a long time, particularly at FEMTO-ST. They have an essential role in many metrological applications such as in positioning devices like GPS, Glonass, Galileo, etc

International audience; The unclear physical origin of flicker noise in ultra-stable quartz oscillators is still limiting some practical metrological applications. In this paper, we study experimentally the possible correlations between Q-factor meas

In this paper, prototypes of SC-cut resonators with 5 MHz resonant frequency are presented. The resulting short-term stability of some resonators has been measured lower than 8·10−-14 in terms of Allan standard deviation. The results are compared
