Abstract

We demonstrate squeezing of a strongly interacting optoelectromechanical system using a parametric drive. By employing real-time feedback on the phase of the pump at twice the resonance frequency the thermomechanical noise is squeezed beyond the 3 dB instability limit. Surprisingly, this method can also be used to generate highly nonlinear states. We show that using the parametric drive with feedback on, classical numberlike and catlike states can be prepared. This presents a valuable electro-optomechanical state-preparation protocol that is extendable to quantum regime.
