THE OPTICAL TRANSMISSION OF ONE-DIMENSIONAL PHOTONIC CRYSTAL

In this article we used our own MATLAB algorithm based on the transfer matrix method (TMM) to simulate the transmission of a one-dimensional photonic crystal composed of two layers: A = SiO(2) and B = TiO(2) with the corresponding refractive indexes n(A) = 1.45 and n(B) = 2.65. The studied structures were generated starting from the one-dimensional Thue-Morse sequence, for example: (AB)(16), (ABBA)(8) and (ABBABAAB)(4). We analyze the influence of various defects: the type of the material used in the defect layer (TiO(2), As(2)Se(3)) thickness and position of the defect layer, upon the optical transmission. Our simulations for such photonic crystals with a photorefractive defect layer show a possible application of these types of structures to optical commutation.
