基于OPA-环形腔光力学系统的纠缠特性研究
|
摘要
研究了一个包含光学参量放大器在内的由两个可移动全反射的镜子和一个固定的部分透射腔镜构成的环形腔光力学系统。通过数值模拟纠缠对数负值,发现光学参量放大器可以影响腔场和可移动镜子之间纠缠。研究发现,腔场和可移动镜子之间鲁棒性会随着非线性增益增加而增加。由此,我们实现了一种利用光学参量放大器对腔场和可移动镜子之间最大纠缠值操控的方法。
This paper studies a ring cavity ophotomechanics system consisting of two removable fully reflective mirrors and a fixed partial transmission mirror that includes an optical parametric amplifier. By numerically simulating the logarithmic negative value of entanglement,it is found that the optical parametric amplifier can affect the entanglement between the cavity field and the movable mirror. It is also found that the robustness between cavity and movable mirrors increases along with the increase of nonlinear gain. So we have got a method of manipulating the maximum entanglement value between the cavity field and the movable mirror by using an optical parametric amplifier.
