Effect of Phase Noise on the Stationary Entanglement of an Optomechanical System with Kerr Medium

We theoretically investigate the effect of phase noise on the stationary entanglement of an optomechanical system, which has the additional Kerr medium in the cavity. There are two kinds of interactions in the system, photon-mirror interaction and photon-photon interaction. We find that the optomechanical entanglement can be suppressed by the phase noise of the pumping laser and Kerr interaction of photons. We also find that Kerr interaction can make the phase-noise-induced double peak of the stationary entanglement change to a single peak.
