We consider an optomechanical (OM) system driven continuously close to resonance. The OM interaction generates correlation between light and mechanical motion: OM entanglement. The same correlation is encoded in the two sidebands of the cavity output field. Detecting entanglement on two appropriate light modes reveals the presence of OM entanglement.
We present a scheme that is portable to various optomechanical set-ups, for instance membrane in the middle or levitated particles. The tools developed can treat the presence of multiple mechanical modes in the frequency response of the OM system.
Fully analytical study of the Langevin eq. and simulations of realistic situation predict entanglement for accessible parameter regime.
