“…We consider the case of M = N = K = 5, since these numbers of the cells is sufficient to ensure abrupt boundaries of the bandgaps and pronounced and well distinguishable transmission bands (see our papers [19,20]. The dielectric permittivities of the materials are chosen to be corresponding to the room temperature t0 [23,24,31,34]. The light and dark areas in Fig.…”

“…All these materials are optically isotropic and the normal modes of the considered PC are the electromagnetic waves of TE-and TMpolarizations. The chosen oxides are transparent in the wavelength range (1-5) μm, and the frequency dispersion of their dielectric permittivities are well described by Sellmeier equations [22][23][24][25].…”

We study the influence of thermal expansion and thermo-optic effect on optical properties of finite one-dimensional three-periodic photonic crystals of structure [(ab) N (cd) М ] K composed of four different nonmagnetic dielectric materials a, b, c, and d. We calculate temperature dependencies and incidence angle dependencies of the transmittivity of TE-and TM-polarized electromagnetic waves, as well as the distribution of energy within these structures. The optimal adjustment of photonic crystal bandgap centers for obtaining the desired transmission characteristics of the temperature-governed photonic bandgap structures is found, and the peculiarities of the energy distributions inside the photonic system are investigated. We propose a sensitive thermal polarization TE|TM switch as well as angular and temperature sensors working at the intraband-mode frequencies exploiting temperature effects.
