In this study, the transfer matrix method is used to analyze the optical properties of a layered structure, {Air(SrTiO3/BSCCO)20Substrate}, consisting of air, SrTiO3, BSCCO (bismuth strontium calcium copper oxide) bilayers, and a substrate. This paper aims to investigate the transmittance spectra of two proposed one-dimensional (1D) structures, including a conventional superconductor photonic crystal (PC) and a gyroidal superconductor PC at infrared (IR) wavelengths. A comprehensive analysis has been carried out to provide useful insights into the optical properties and the behavior of the proposed structure, highlighting the impact of many parameters, such as refractive index, filling fraction, and layer thickness. The numerical findings showed that the permittivity of the BSCCO superconductor of a gyroidal geometry takes a different response compared to the conventional one. Notably, the filling fraction and refractive index of the host material have a significant control on both real and imaginary parts of the gyroidal BSCCO permittivity through the considered wavelengths. Thus, the proposed design provides high transmittivity outside the obtained photonic band gap compared to the conventional one. We believe that the designed one-dimensional gyroidal BSCCO photonic crystals could act as an efficient reflector through near IR for optoelectronics and energy applications.

一维螺旋超导光子晶体的透射率特性

在本研究中，采用传递矩阵方法来分析层状结构{Air(SrTiO3/BSCCO）20基材}，由空气、SrTiO组成3、BSCCO（铋锶钙铜氧化物）双层和基底。本文旨在研究两种提出的一维（1D）结构，包括传统超导光子晶体（PC）和螺旋超导PC在红外（IR）波长下的透射光谱。我们进行了全面的分析，为所提出的结构的光学特性和行为提供了有用的见解，强调了许多参数的影响，例如折射率、填充分数和层厚度。数值结果表明，与传统超导体相比，螺旋几何形状的 BSCCO 超导体的介电常数具有不同的响应。值得注意的是，主体材料的填充分数和折射率在所考虑的波长范围内对陀螺 BSCCO 介电常数的实部和虚部都有显着的控制。因此，与传统设计相比，所提出的设计在所获得的光子带隙之外提供了高透射率。我们相信，设计的一维陀螺 BSCCO 光子晶体可以作为近红外的有效反射器，用于光电和能源应用。
