ABSTRACT: We investigate quantum bipartite entanglement between mechanical and polarized optical modes in a lossy optomechanical cavity driven by a polarized electromagnetic field. A key feature of our scheme is that the polarization of the driving field permits phase-dependent modulation of the components of the optomechanical coupling strength. We demonstrate that this modulation offers a precise control mechanism, enabling the generation of optomechanical entanglement primarily oriented along a desired direction (vertical or horizontal). The intracavity loss acts as a resource, leading to an enhancement of the generated polarized optomechanical entanglements. Moreover, this loss is shown to be crucial for significantly increasing the robustness and stability of the generated entanglement against thermal noise. This work paves the way for advanced quantum state engineering and robust quantum information processing protocols within optomechanical systems.
