Abstract: (6065 Views)
In this study, we theoretically investigate the possibility of entanglement generation and swapping between different modes of coupled optomechanical arrays in the presence of OPA nonlinearity. As can be seen, in this setup, the presence of OPA media, which can increase the mean photon number and consequently the optomechanical coupling constant, lead to stronger entanglement between adjacent and distant modes of optomechanical systems in comparison with bare ones. Moreover, by using these nonlinear media, the steady state entanglement between different modes of arrays in stable regime, become more robust against temperature.
