Dynamics of optomechanically coupled mirrors — •Jan Harms — Albert-Einstein-Institut,Am Kleinen Felde 30,30167 Hannover

The dynamics of optical systems which store light by means of suspended mirrors give rise to optical springs via an optomechanical coupling between the mirrors and the light. These springs transform the free motion of the mirrors into the motion of coupled oscillators with resonances at low acoustic frequencies. Consequently, interferometric detectors which exhibit optomechanical resonances are more sensitive to signals at frequencies close to the resonance frequencies and theoretically, measurements below the quantum limit are possible. A deeper understanding of the dynamics of such systems may help to design new topologies in order to achieve the best sensitivity within the detection frequency band.
