Study on the transmission properties of Thue - Morse sequence one - dimensional superconducting photonic crystals

The superconducting photonic crystal is an important tunable photonic crystal.The transmission properties of the 1D Thue-Morse sequence photonic crystals consisting of alternating superconductor and dielectric layers in visible region were theoretically investigated by using the transfer matrix method.The numerical results show that in the normal incidence the bandwidth and the position of the photonic band gap are invariant with the increases of the sequence terms in general.Moreover the transmission property can be controlled by changing the structural parameters of the dielectric materials and the ambient temperatures.
