基于三模系统的复合光子阻断

Compound photon blockade based on three mode system

Hongyu Lin

摘要:

基于四波混频,提出了一种三模非线性系统。通过解析分析和数值计算讨论了单光子阻塞效应。解析分析表明,常规光子封锁和非常规光子封锁可以同时实现,且两种封锁的解析条件相同。数值计算结果表明,该系统不仅在封锁区具有最大平均光子数,而且在非线性耦合系数较小的区域也能产生较强的光子反聚束,大大降低了系统的实验难度。该光学系统能够实现复合光子阻塞效应,有助于实现高纯度的单光子源。

英文摘要:

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.
