In the present work, we demonstrate the generation of Fano resonance (F) feature based on a defected one dimensional superconducting photonic crystal design. Our proposed design consists of alternated layers of high-temperature superconductor material with conventional ones. By using the transfer matrix method, we investigate the optical properties for the proposed designs. The obtained optical properties show two sharp peaks with zero side band of reflectivity are resulted NIR region. Then, by adding a defect layer to the periodic structure, we find that two peaks are appeared in the obtained spectrum which they are indicated for electromagnetic induced reflection (EIR) and Fano resonance concept. Finally, by adjusting the design parameters of our proposed structure such as the number of periods, the thickness of the constituent layers, and the refractive index of defect layer, we investigated the corresponding optical properties response. Our proposed designs can be used in so...

有缺陷的一维超导光子晶体设计,用于产生法诺共振特征

在目前的工作中,我们演示了基于有缺陷的一维超导光子晶体设计的Fano共振(F)特征的产生。我们提出的设计包括高温超导体材料与常规材料的交替层。通过使用转移矩阵方法,我们研究了所提出设计的光学性质。所获得的光学性质显示出具有近乎零的反射率边带的两个尖峰,是得到的NIR区域。然后,通过在周期性结构中添加缺陷层,我们发现在获得的光谱中出现了两个峰,这些峰分别表示为电磁感应反射(EIR)和Fano共振概念。最后,通过调整我们提出的结构的设计参数,例如周期数,组成层的厚度,以及缺陷层的折射率,我们研究了相应的光学性能响应。我们提出的设计可用于...
