“…This implies the absence of transmission for signals with frequencies within a given interval of values. Such a property is highly useful in applications involving optical devices [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. For these applications, it is essential to tune the properties of PBGs and to obtain the widest possible band gaps.…”

“…For example, metals exhibit inherent losses, which are caused by the extinction coefficient. To overcome these problems, a variety of unconventional materials have been used, such as superconductors [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In superconductors, optical properties are strongly influenced by temperature and magnetic fields.…”

In this study, we perform a theoretical study of light propagation properties in two-dimensional square photonic crystals (PCs) following Bravais–Moiré (BM) patterns composed of copper oxide high-temperature superconductors (HTSCs). The BM PCs are made of cylindrical cores formed from the combination of two square Bravais lattices. The Moiré pattern forms due to a commensurable rotation of one of these lattices with respect to the other. The dielectric function of the superconducting material is modeled by the two-fluid Gorter–Casimir theory. We report on the corresponding gap, the mapping as a function of the radius of dielectric cores, as well as the dispersion relations of TM modes for BM PCs and for the waveguide system built of defect lines within such a crystal. The BM PCs were composed of copper oxide HTSCs, which exhibit large tunability in terms of temperature.
