摘要
本文提出在Fabry-Perot腔和光学参量放大复合系统中实现非常规光子阻塞效应.此系统包含可调谐的复合型驱动强度相位,用二阶关联函数描述光子统计性质,数值模拟不同参数下的光子阻塞效应,研究发现通过调节复合型驱动强度相位可以控制非常规光子阻塞.在弱驱动条件下,计算得到了强光子反聚束的最优化条件,并给出了二阶关联函数解析式,研究发现数值模拟结果与解析结果相符合.研究结果为光子阻塞的相干操作提供了平台,在量子信息处理和量子光学器件等方面具有潜在的应用前景.
In this paper, we present a scheme to realize an unconventional photon blockade effect in a Fabry-Perot cavity and optical parametric amplifier(OPA) composite system. The system includes a tunable phase of complex driving strength, the second-order correlation function is used to describe the photon statistical properties. The numerical simulation of the photon blockade effect is conducted with different parameters. Our calculations show that the unconventional photon blockade effect can be controlled by the tunable phase of complex driving strength. Under the weak driving condition, the exact optimal conditions for strong photon anti-bunching are analytically derived(i.e. the optimal nonlinear gain of optical parametric amplifier and the phase of the field driving for the strong photon anti-bunching are obtained), and obtain the analytic calculations of the second-order correlation function. Under the optimal conditions, we perform a numerical simulation with different parameters. The optimal conditions for strong photon anti-bunching are found by analytic calculations, which are in good agreement with the numerical results. The results provide a platform for coherently operating the photon blockade and have potential applications in quantum information processing and quantum optical devices.
