• Band edges show blue-shift with increasing incident angle for both structures.
• By increasing structure thicknesses, band edges show red-shift.
• TM gaps are closed at an incident angle about 0.7 rad.
• At temperature T = 73 K all PBGs in the transmission spectra are eliminated.
• Wave front of propagating field in the Rudin-Shapiro is wider than other structures.
The present paper attempts to determine the properties of photonic spectra of Thue-Morse, double-period and Rudin-Shapiro one-dimensional quasiperiodic multilayers. The supposed structures are constituted by high temperature HgBa2Ca2Cu3O10 and YBa2Cu3O7 superconductors. Our investigation is restricted to the visible wavelength domain. The results are demonstrated by the calculation of transmittance using transfer matrix method together with Gorter-Casimir two-fluid model. It is found that by manipulating the parameters such as incident angle, polarization, the thickness of each layer and operation temperature of superconductors the transmission spectra exhibit some interesting features. This paper, provides us a pathway to design tunable total reflector, optical filters and optical switching based on superconductor quasiregular photonic crystals.
