Mechanically driven coherent photon dynamics in optomechanical systems — •Georg Heinrich¹, Jack Harris^1,2 und Florian Marquardt¹ — ¹LMU, Department für Physik, ASC, CeNS, München, Germany — ²Yale University, Department of Physics, Department of Applied Physics, New Haven, CT, USA

The motion of micro- and nanomechanical objects can be coupled to electromagnetic fields. Such optomechanical systems provide new means to manipulate both light as well as mechanical motion and allow to explore the interaction of light and matter in a new regime at the boundary between quantum and classical physics. Besides the objective to eventually explore the quantum regime of mechanical motion, there have been several studies of the complex nonlinear dynamics of these systems. A recent development has introduced setups with multiple coupled optical and vibrational modes pointing the way towards integrated circuits. Here we present non-equilibrium photon dynamics in multimode systems due to the application of external, mechanical driving. This mechanically driven coherent photon dynamics can introduce the whole domain of strongly driven two- and multilevel systems to the field of optomechanics. In particular we consider the recently introduced setup consisting of a movable membrane, placed in the middle between two high-finesse mirrors, that tunnel-couples two optical modes residing in the left and the right half of the cavity, respectively. For mechanical driving of the membrane we predict Autler-Townes splittings, Rabi processes and Landau-Zener-Stueckelberg dynamics, all observable in the transmission spectrum of the system.
