论文摘要
我们提出了一种方案，以在高度无法解决的边带（HURSB）制度中产生强大而稳健的机械挤压，借助于悬挂非线性和腔内挤压光。该系统是由标准的光机械系统形成的，具有非线性（机械非线性）和二阶非线性培养基（光学非线性）。在解决的边带状态中，二阶非线性介质在机械挤压的产生中可能起破坏性作用。但是，它可以显着增加HURSB政权中的机械挤压（大于3DB）。最后，我们显示机械挤压对机械谐振器的热波动是可靠的。在HURSB制度中产生大型且健壮的机械挤压是机械和光学非线性的综合效果。
We propose a scheme to generate strong and robust mechanical squeezing in an optomechanical system in the highly unresolved sideband (HURSB) regime with the help of the Duffing nonlinearity and intracavity squeezed light. The system is formed by a standard optomechanical system with the Duffing nonlinearity (mechanical nonlinearity) and a second-order nonlinear medium (optical nonlinearity). In the resolved sideband regime, the second-order nonlinear medium may play a destructive role in the generation of mechanical squeezing. However, it can significantly increase the mechanical squeezing (larger than 3dB) in the HURSB regime. Finally, we show the mechanical squeezing is robust against thermal fluctuations of the mechanical resonator. The generation of large and robust mechanical squeezing in the HURSB regime is a combined effect of the mechanical and optical nonlinearities.
