Steady-state control in an unstable optomechanical system
Abstract
We demonstrate the stabilization of an unstable steady state in an optomechanical system for low and high pump rates. The optomechanical system consists of a pumped cavity with one movable mirror. The stabilization is achieved by applying Pyragas control, i.e., feeding back the cavity field by an external mirror. This way, a maximal cavity field in the low pumping regime can be achieved, which corresponds to a large displacement of the movable mirror.
