Abstract

Optical properties of generalized dielectric Fibonacci multilayer generated by the rule S_l+1 = Sⁿ _l S^m _l-1 with a pair of positive integers m and n were studied. The initial generations S1 and S2 are taken as S₁ = H and S₂ = L where H and L are two elementary layers with refractive indices n_L = 1.45 and n_H = 2.3, respectively. In the following numerical investigation, we chose SiO₂ (L) and TiO₂ (H) as two elementary layers. We use the so-called "antitrace" map to determine the transmission spectra of the structures. Based on the representation of the transmittance spectra in the visible range an analysis depending on the pair (n,m) is presented. We show that the whole structure Sⁿ _l S^m _l-1 has an interesting application for well selection pairs (m, n) values.
