We consider a three-waveguide (WG) directional coupler with an attempt to explore an optical analogue of the quantum coherence dynamics, which is found to be achievable in the present model at the macroscopic domain. In order to simulate the characteristics of such opto-quantum analogy, a field-coupled three-level atomic system has been undertaken in our study. Mutual correspondence between the field-induced coherence properties in the atomic system and the light transfer related optical properties in the evanescently coupled WGs has been discussed in the dissipative cases at different parameter conditions. The signature of optical impedance is highlighted in this context and the impact of these terms in visualizing the coherence dynamics inherent to a nano-photonic structure is explicitly reported.

使用三波导定向耦合器在宏观域中模拟量子相干动力学

我们考虑了一个三波导 (WG) 定向耦合器，试图探索量子相干动力学的光学模拟，这在宏观域的当前模型中是可以实现的。为了模拟这种光量子类比的特性，我们在研究中进行了场耦合三级原子系统。已经在不同参数条件下的耗散情况下讨论了原子系统中场致相干特性与渐逝耦合WG中与光传输相关的光学特性之间的相互对应关系。在这种情况下突出了光阻抗的特征，并明确报告了这些术语在可视化纳米光子结构固有的相干动力学方面的影响。
