研究了一个处于λ组态的三能级原子与微腔的耦合。假设原子的两个跃迁耦合到腔中不同的对向传播模对。我们分析了强耦合和坏腔极限下的动力学。我们发现，相比于一个两级设置，第三原子状态和额外的控制场模式至关重要地修改系统动力学，使更先进的控制方案。所有的结果解释使用适当的缀饰态和本征模表示。作为潜在的应用，我们讨论了光开关和旋转门操作和检测靠近谐振腔表面的粒子。
A three-level atom in the {Lambda} configuration coupled to a microcavity is studied. The two transitions of the atom are assumed to couple to different counterpropagating mode pairs in the cavity. We analyze the dynamics both in the strong-coupling and the bad-cavity limits. We find that, compared to a two-level setup, the third atomic state and the additional control field modes crucially modify the system dynamics and enable more advanced control schemes. All results are explained using appropriate dressed-state and eigenmode representations. As potential applications, we discuss optical switching and turnstile operations and detection of particles close to the resonator surface.
