计算了两个弱克尔非线性耦合腔被同时驱动下的归一化二阶关联函数。经分析计算发现了强反聚束的优化条件,分析结果同数值模拟非常符合。同时分析了在优化条件下参数的变化对强反聚束的影响。

The normalized second-order correlation function was calculated for a system of two coupled cavity modes with weak Kerr nonlinearity and the two cavity modes were driven simultaneously. The optimal conditions for strong antibunching were found by analytic calculations, which coincided well with the numerical results. The change range of the parameters was studied under the optimal conditions for strong antibunching.
