【 摘 要 】

The results of theoretical and numerical studies of finite one-dimensional (1D) three-periodic photonic crystals of the structure [(ab)(3)(cd)(3)](3), consisting of four different materials (dielectric oxides Al2O3, SiO2, TiO2, and ZrO2) are presented. We study the transmittivity spectra and partial energy fluxes of the TE- and TM-modes in the range of 1-5 mu m in the vicinity of the first photonic bandgap depending on the incidence angle and frequency of light. The obtained results can be used to create precise polarization-sensitive devices for an inputoutput of the radiation into an optical fiber. The optimization of the considered multiperiodic structures has been achieved at the telecommunication wavelength 1.55 mu m both by changing incidence angle and adjusting the topology (i.e. thicknesses of the constituent layers). We discuss a principle of a new type of polarization splitter on the basis of three-periodic photonic crystal.
