Transmission Properties of Thue-Morse Quasi-Periodic 1D Superconducting Photonic Crystals

Abstract

The transmission properties of Thue-Morse quasi-periodic one-dimensional photonic crystals (1DPCs) containing superconducting material are theoretically investigated based on the transfer matrix method. It is shown that the 1DPCs can possess a same photonic band gap property as the periodic structure superconducting PC. The results of transmittance spectra show that the cutoff frequency can be manipulated through the thicknesses of the superconductor and dielectric layers as well as the ambient temperature of the system. It is observed that the shift of cutoff frequency becomes more noticeable by adjusting the thickness of the superconductor layer than that of the dielectric one. Furthermore, the cutoff frequency becomes very sensitive when the system temperature is tuned to close vicinity of the critical temperature of the superconductor.

Studies of Optical Properties of Symmetrical Quasi-Periodic Photonic Crystals

“…For the optimal value j = 8, we study the reflection spectra properties of the configuration H(LH) 8 /T m /H(LH) 8 for different values of m. It should be noted that we choose the even number of m because the Thue-Morse with even iteration values can be builds a symmetric system. Figure 9 shows the reflection spectra generated by this hybrid photonic system.…”
