In this paper we investigate the photonic tunneling effect between two coupled one-atom laser cavities. The physical system consists of two coupled photonic crystal microcavities and each cavity contains a coherently pumped two-level atom. The dynamics of the system can be described by the master equation in terms of the reduced density operator. It is shown that the photonic tunneling behavior depends on certain physical conditions of the system. In the absence of the pumping field andwithout dissipations, the coherent photon number imbalance
between two cavities exhibits the alternating-current Josephson effect.
在本文中，我们要探讨两个耦合单原子激光腔的光（量）子隧道效应。这个物理系统由两个耦合的光子晶体微腔组成，并且每个腔内都包含一个相干的两能级泵激原子。该系统的动力学原理可以按照约化密度算子的主方程式来进行解释。它表明，光子隧道的反应要依据特定的物理条件而定。在缺乏注入场和耗散的情况下，在两个腔内的相干光子数量的不平衡显示出交变电流的约瑟夫森(隧道)效应。
However, when the pumping effect and losses of the system are taken into account, the mean photon number imbalance displays a damped oscillation. In addition, the influence of tunneling amplitude and photonic band-gap structure on the oscillations is also studied. The research gives a further insight into the correlated dynamics of two coupled one-atom laser systems and
provides an idea for constructing novel photon tunnel devises.
然而，当将抽运效应和该系统的损失计算在内，这个平均光子数不平衡将显示出阻尼振荡。另外，该隧道的幅度和在震荡上的光子带隙结构的影响也需要进行研究。该研究为两个耦合的单原子激光系统的动力学提供了更深一步的研究见解并为构建新型光子隧道设备提供了一个很好的想法（研究基础）。 |
