Abstract: On this paper, we present an in depth evaluation of the bipartite entanglement of cavity radiation from the optomechanical device with an optical parametric amplifier (OPA) placed inside two cavity mode, which together have interaction with a mechanical resonator. Right here by linearizing the equations of motion, we set the entanglement gift inside the gadget, the use of the logarithmic negativity as a degree. We thereby symbolize the adjustments inside the machine entanglement that result from the addition of an quadratic coupling to a linearly coupled gadget. With the assist of the optical parametric amplifier, the desk bounds macroscopic entanglement between the movable replicate and the hollow space subject can be mainly more suitable, and the degree of entanglement increases while the parametric gain increases as well as input laser electricity will increase. For that reason, while an optical parametric amplifier is delivered inside a hollow space, which leads to extensive improvement of the two-mode entanglement. These results establish a promising theoretical basis for optical parametric amplifier (OPA) more suitable bipartite entanglement of optomechanical device for quantum technology and advanced quantum information processing applications.
