Observation of generalized optomechanical coupling and cooling on cavity resonance
Andreas Sawadsky, Henning Kaufer, Ramon Moghadas Nia +4
Optomechanical coupling between a light field and the motion of a cavity mirror via radiation pressure plays an important role for the exploration of macroscopic quantum physics an…
Anomalous dynamic back-action in interferometers
Sergey P. Tarabrin, Henning Kaufer, Farid Ya. Khalili +2
We analyze the dynamic optomechanical back-action in signal-recycled Michelson and Michelson-Sagnac interferometers that are operated off dark port. We show that in this case --- a…
Tomographic readout of an opto-mechanical interferometer
Henning Kaufer, Andreas Sawadsky, Tobias Westphal +2
The quantum state of light changes its nature when being reflected off a mechanical oscillator due to the latter's susceptibility to radiation pressure. As a result, a coherent sta…
