摘要：

The properties of one-dimensional photonic quasicrystals built according to one-dimensional-generalized Fibonacci (GF)/Generalized Thue-Morse (GTM) were investigated in order to design an output polychromatic filter. This main aperiodic multilayered structure was made up of alternate two dielectrics materials Silica and Bi4Ge3O12 (BGO)with higher and lower refractive indices respectively. The Transfer Matrix Method (TMM) was adopted to calculate the photometric response. The transmittance spectrum exhibited a stacking of similar Bragg gaps (BGs) for specific arrangement (m = n) of GF and GTM. We noted that the positions and the number and size of BGs were sensitive to the constituent of the Photonic quasicrystal (PQC) system and lattice parameter of quasiperiodic sequence. Therefore, these configurations of multilayered stacks can be useful as a graded polychromatic filter.
