A 1D photonic crystal structure contains 16 layers, 8 common dielectrics and another 8 one nonlinear media, with an arrangement similar to 5-seriy of Thue-Morse is presented. In this structure, the properties of band-gape, optical multistability are investigated. On the band gap, 5 resonant modes are observed. On the behavior of output intensity versus input intensity around resonant frequencies, the multistability response observed. When the frequency of incident filed is close to resonant frequency, the threshold of multistability is decreased.
