Transmittance spectrum in a one-dimensional photonic crystal with Fibonacci sequence superconductor ? semiconductor

In this work, we use the transfer matrix method to calculate the transmittance spectrum in a quasi-periodic one-dimensional photonic crystal (1D-PC) consisting of superconducting materials (HgBa2Ca2Cu3O8+δ) and semiconductor (GaAs). The distribution of the layers of the materials depends on the Fibonacci sequence. The dielectric constant and thickness of the semiconductor depend on the hydrostatic pressure applied, as does the critical temperature of the superconductor. The numerical results reveal a significant shift of the photonic band gap at larger frequencies when the pressure is increased by keeping the temperature constant. An increase in the number of photonic band gap is found when both the angle of incidence of the light and the thicknesses of the materials are increased. Additionally, the number of resonance peaks in the resonance spectrum increases as the Fibonacci sequence increases. © 2020 Elsevier GmbH
