We analyze the influence of correlations on the optical properties of disordered metallic photonic crystal slabs experimentally and theoretically. Different disorder models with different nearest-neighbor correlations are considered. We present a theory that allows us to quantitatively calculate the optical properties of the different samples. We find that different kinds of correlations produce characteristic spectral features such as peak reduction and inhomogeneous broadening. These features are caused by reduced excitation efficiencies and the excitation of multiple resonances.
我们通过实验和理论分析了关联对无序金属光子晶体平板光学性质的影响。考虑了具有不同最近邻关联的不同无序模型。我们提出了一种理论，该理论使我们能够定量计算不同样品的光学性质。我们发现不同类型的关联会产生特征光谱特征，如峰值降低和非均匀展宽。这些特征是由激发效率降低和多重共振的激发引起的。
