contents We propose a scheme to generate robust optomechanical entanglement. This scheme is based on a Backward Stimulated Brillouin Scattering (BSBS) process, which is hosted within an optomechanical structure. Our benchmark system consists of an acoustic (mechanical) mode coupled to two optical modes through the BSBS (radiation pressure) process. For a moderate values of the effective mechanical coupling, the BSBS induces a relatively weak entanglement. This entanglement is greatly enhanced, for at least up to one order of magnitude, when the mechanical coupling strength is strong enough. The generated entanglement is robust enough against thermal fluctuation. Our work provides a new scheme for entanglement generation based on BSBS effect, and can be extended to microwaves and hybrid optomechanical structures. Such a generated entangled states can be used for quantum information processing, quantum sensing, and quantum computing.
