论文摘要
在最近的出版物中[物理学。 Rev. B 87，235319（2013）]，在二阶非线性系统中研究了低频模式的常规光子阻滞（CPB）。在本文中，我们将在二阶非线性系统中研究高频模式的CPB，在低频腔中具有KERR非线性填充。通过求解主方程并计算零 - 列表的二阶相关函数$ g^{（2）}（0）$，可以在高频腔中获得强的光子抗发机。通过分析量表可以找到强烈抗挑战的最佳条件，并提出了最佳条件的讨论。我们发现Kerr-非线性可以增强CPB效应。此外，该方案对储层温度不敏感，这使得当前系统更易于实验实现。
In the recent publication [Phys. Rev. B 87, 235319 (2013)], the conventional photon blockade(CPB) was studied for the low frequency mode in a second-order nonlinear system. In this paper, we will study the CPB for the high frequency mode in a second-order nonlinear system with the Kerr nonlinearity filling in the low-frequency cavity. By solving the master equation and calculating the zero-delay-time second order correlation function $g^{(2)}(0)$, strong photon antibunching can be obtained in the high frequency cavity. The optimal condition for strong antibunching is found by analyticcal culations and discussions of the optimal condition are presented. We find that the Kerr-nonlinearities can enhanced the CPB effect. In addition, this scheme is not sensitive to the reservoir temperature, which make the current system easier to implement experimentally.
