Theoretical studies of hybrid multifunctional YaBa2Cu3O7 photonic crystals within visible and infra-red regions

In this paper, the optical spectra of one-dimensional photonic crystal (PCs) are numerically investigated in UV, Visible and Infrared ranges. PCs consisting of a HTc superconducting material (YaBa(2)Cu(3)O(7)) are sandwiched between dielectric layer (SiO2 or AlN) and semiconductor layer (GaAs), where superconducting layer is considered as defects. Using transfer matrix method, all the numerical results are performed and inferred that photonic band gap shifted to higher wavelengths by increasing the temperature. It is found that when the temperature increases the PBG shifted to a long wavelength. When the defect is used in structure as dielectric or superconductor, the peak appears in PBG and his value increases as the temperature increases.
