Analysis of Photonic Bandgap Extension in One-Dimensional Quasiperiodic Superconducting Photonic Slabs

Abstract

One-dimensional superconducting photonic slabs made of alternated layers of isotropic dielectric (SiO2) and a high-Tc superconductor (YBCO) are theoretically investigated by the Gorter Casimir two fluid model (GCTFM) and the transfer matrix method (TMM). The proposed photonic quasicrystals are built according to the inflation rule of quasiperiodic sequences. The enhancement of the photonic band gap is theoretically investigated. Extending photonic band gap (E-PBG) is achieved for suitable quasiperiodic chains. The bandwidth of the photonic band gap can be enhanced by changing the temperature of superconductor, parameter of quasiperiodic sequence. An overall photonic band gap is obtained in the visible frequency range and can be enhanced by applying a typical thickness’ deformation along the superconducting photonic sample.
