Nonlinear interaction effects in a strongly driven optomechanical cavity

arXiv:1304.4197 · doi:10.1103/PhysRevLett.111.053602

Abstract

We consider how nonlinear interaction effects can manifest themselves and even be enhanced in a strongly driven optomechanical system. Using a Keldysh Green's function approach, we calculate modifications to the cavity density of states due to both linear and nonlinear optomechanical interactions, showing that strong modifications can arise even for a weak nonlinear interaction. We show how this quantity can be directly probed in an optomechanically-induced transparency type experiment. We also show how the enhanced interaction can lead to nonclassical behaviour, as evidenced by the behaviour of g_2 correlation functions.
