Abstract

We propose a scheme for the entanglement generation of two micromechanical mirrors through two-mode fields generated by a correlated emission laser source in a doubly resonant cavity. The coherence between upper and lower levels is generated in a cascade-driven scheme using two external classical fields. Two input laser fields are both tuned at the Stokes sidebands such that cooling and entanglement of micromechanical mirrors are realizable. We investigate two different conditions for entanglement generation. We show controllable entanglement of both two-mode fields and two mirrors in the steady state. The proposed scheme for the macroscopic entanglement generation is robust against environmental thermalization and in favor of a large cavity dissipation rate.
