To investigate the reflection of light in quasi‐regular dielectrics, we study here the optical properties of porous‐silicon‐based Fibonacci, Thue‐Morse and Period Doubling heterostructures. The multilayered systems are fabricated in such a way that each element in the two‐block substitutional sequence has a poly‐type structure. Both delta‐like and traditional configurations are considered. The results for the optical transmittance are analyzed and compared with the classical periodic structure. Numerical simulation for the transmittance along the lines of the transfer matrix approach is also presented. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
