本文提出并研究了一种将电磁感应透明(EIT)效应引入耦合腔光波导(CROW)可控带隙结构中光子相干传输的混合机制。在这里，系统的组态结构由一个均匀耦合的Crow和每个腔中掺杂了Lambda类型三能级的人造原子组成。在平均场方法的基础上，三能级原子的作用被完全考虑，在平均场方法中，三能级原子的集合共同表现为双模自旋波。结果表明，耦合玻色子模型可以有效地描述原子系综的低激发动力学。精确解表明，通过绝热控制经典光场，光脉冲可以被相干地阻止和存储。
In this paper, we propose and study a hybrid mechanism for coherent transmission of photons in the coupled resonator optical waveguide (CROW) by incorporating the electromagnetically induced transparency (EIT) effect into the controllable band gap structure of the CROW. Here, the configuration setup of system consists of a CROW with homogeneous couplings and the artificial atoms with Lambda-type three levels doped in each cavity. The roles of three levels are completely considered based on a mean field approach where the collection of three-level atoms collectively behave as two-mode spin waves. We show that the dynamics of low excitations of atomic ensemble can be effectively described by a coupling boson model. The exact solutions show that the light pulses can be stopped and stored coherently by adiabatically controlling the classical field.
