论文摘要
我们提出了一个用于激子诱导的透明度（EXIT）的微观模型，该模型由由发射器组成的杂种系统与金属 - 二电结构中的表面等离子体共耦合。我们获得了这种系统的有效光学极化，并在能量传输速率方面表达的系统组件之间耦合。我们证明，在弱耦合方案中，退出的潜在机制是等离子体和发射极之间的能量交换不平衡。我们以分析形式得出一个频率依赖性函数，该函数准确地描述了散射光谱中透明窗口的形状和幅度，并由数值计算支持。
We present a microscopic model for exciton-induced transparency (ExIT) in a hybrid system comprised of an emitter resonantly coupled to a surface plasmon in a metal-dielectric structure. We obtain an effective optical polarizability of such a system with coupling between the system components expressed in terms of energy transfer rates. We demonstrate that, in the weak coupling regime, the underlying mechanism of ExIT is the energy exchange imbalance between the plasmon and the emitter in a narrow frequency region. We derive in analytic form a frequency-dependent function that accurately describes the shape and amplitude of the transparency window in scattering spectra, supported by numerical calculations.
