研究了机械工程二次光机系统中的光子阻塞效应。结果表明，通过对机械元件运动的调制，可以影响系统的能级结构和光子的统计特性。分析了在强抽运条件下提高光子封锁的二阶相关函数。此外，当调节探测光子的频率时，光子阻塞和双光子激发之间存在振荡。该研究提供了一种可实现的方法来增强对光子的操纵，这将进一步支持光子在量子信息科学中的各种应用。
We study the photon blockade effect in a mechanical engineered quadratic optomechanical system. It is shown that the energy level structure of the system and the statistical properties of the photons can both be influenced through the modulation of the motion of the mechanical components. Also, the second-order correlation function is analyzed for which the photon blockade can be enhanced under the strong pumping condition. Furthermore, the oscillation is present between the photon blockade and two-photon excitation when tuning the frequency of the probe photon. The study provides an achievable method to enhance the manipulation of photons, which will further support the various applications of photons in quantum information science.
