Abstract
This oscillator comprises: a source generating an incident optical wave at a pulsation frequency ω; an optomechanical resonator, having optical resonances at the pulsation frequency ω and mechanical resonances at a frequency f1 and generating, from the incident optical wave, emergent optical waves at the pulsation frequencies ω and ω−2πf1, and an acoustic wave at frequency f1; and, a photodiode delivering a useful signal at frequency f1 from the emergent waves. This oscillator further comprises: an acoustic propagation means for propagating the acoustic wave over a distance in order to produce a delayed acoustic wave; a means for converting the delayed acoustic wave into a delay signal at the frequency f1; and, a control loop, processing the delay signal in order to obtain a control signal applied to the source.
