论文摘要
基于四个波混合，提出了三个模式非线性系统。通过分析分析和数值计算讨论了单个光子阻滞。分析分析表明，可以同时实现常规的光子阻滞和非常规光子阻滞，并且两种阻断的分析条件是相同的。数值结果表明，该系统不仅具有封锁区域中最大的平均光子数，而且还可以在该区域具有强烈的光子抗堆积，并具有小的非线性耦合系数，这大大降低了系统的实验难度。可以实现化合物光子阻滞效应的光学系统有助于实现高纯度单光子源。
Based on the four wave mixing, a three mode nonlinear system is proposed. The single photon blockade is discussed through analytical analysis and numerical calculation. The analytical analysis shows that the conventional photon blockade and unconventional photon blockade can be realized at the same time, and the analytical conditions of the two kinds of blockade are the same. The numerical results show that the system not only has the maximum average photon number in the blockade region, but also can have strong photon anti-bunching in the region with small nonlinear coupling coefficient, which greatly reduces the experimental difficulty of the system. This optical system which can realize the compound photon blockade effect is helpful to realize the high-purity single photon source.
