摘要
本文研究了嵌入二能级原子的四波混频耦合系统中的光子反聚束效应,通过对系统进行解析分析,获得了实现光子阻塞的最优条件.接着通过求解稳态极限下的主方程,获得了数值结果.我们发现解析条件下的最优阻塞条件与数值结果保持一致,这表明在该系统中可以实现非传统光子阻塞.进一步详细讨论了系统的几个参数对实现非传统光子阻塞的影响.结果表明,此系统中的四波混频耦合相互作用和原子-腔耦合系数可以大大增强非传统的光子阻塞效应.
Abstract
This paper investigates the photon antifocusing effect in a four-wave mixing coupled system embedded with a two-level atom.Through analytical analysis of the system,we obtain the optimal conditions for achieving photon blockade.Subsequently,numerical results are obtained by solving the main equation in the steady-state limit.Our findings reveal that the analytical optimal conditions are consistent with the numerical results,demonstrating that this system can realize nontraditional photon blockade.Further,a detailed discussion is presented on the influence of various system parameters on achieving nontraditional photon blockade.The results indicate that the four-wave mixing coupling interaction and atom-cavity coupling coefficient significantly enhance the nontraditional photon blockade effect.
