Coherent transmittance and reflectance of multilayers consisting of one-dimensional Fibonacci, Thue-Morse, and periodic sequences of plane-parallel ordered monolayers of spherical alumina and silica particles are investigated in the 0.3 μm to 2 μm spectral range. Consideration is based on the quasicrystalline approximation for individual monolayers and the transfer matrix method for multilayers. Comparison with sequences of the homogeneous plane-parallel layers is made. It is shown that the Fibonacci and Thue-Morse structures provide more possibilities to control light in comparison with the regular ones. These results can be used for the development of optical lters, solar cells, light emitting diodes, displays, etc.
Keywords: photonic crystal, non-periodic sequence, quasicrystalline approximation, transfer matrix method, coherent transmittance and reflectance.
