High-Q Optical Resonators for Stabilization of High Spectral Purity Microwave Oscillators
Résumé
Different high-Q optical resonators are presented in this communication. Our aim is to use them to develop compact high performances microwave oscillators. The optical quality factor of a quartz disk used as a whispering gallery modes resonator has been measured to be higher than 10^9. We also investigate the potentialities of high-Q fibre ring resonators. The performances of an optoelectronic oscillator at 10 GHz based on such a passive fibre ring resonator are presented here.
