Opis:: We have observed a Zeeman effect in an evanescent wave absorption in Rb vapor with a single-mode tunable diode laser. The spectra are obtained for several magnetic field- and laser light-configurations enabling the observation of different pi and sigma Zeeman split lines contribution. The relative amplitudes and relative frequencies of all Zeeman components were calculated theoretically and compared with measured spectra. The analysis of the data can lead to the determination of the polarization state of the evanescent wave.

Opis:: We present a theoretical research of the optical properties of the (3,12,12) hexagonal 2D Archimedean photonic crystals. The structures are made of GaAs dielectric rods in air. Our research is mainly focused on analyzing symmetry properties of the modes and the appearance of the uncoupled modes which strongly affects the propagation of the wave and the optical performances of the material.

Opis:: From various types of scintillating materials lutetium-yttrium oxyorthosilicate (LYSO) has the highest luminosity and the greatest potential of application in high-energy radiation detectors. Due to the small critical angle of total internal reflection the enhancement of the extraction of light outside a scintillator is a challenge. We study numerically the influence of the effective refractive index layer on the transmittance of LYSO crystal. It is possible to realize such layer by sub-wavelength patterning of crystal surface using for example focused ion beam. The enhancement of transmittance of LYSO crystal up to 100% as well as the possibility to tune the positions of transmittance maxima have been shown.

Opis:: Experiments on hot rubidium vapor as an atomic medium with electromagnetically induced transparency for radiation of 795 nm wavelength (D1 absorption line of rubidium) are reported. Propagation of light pulses with velocity reduced to 11.5 km/s has been observed with a significant modification of the shape of square input pulses to adapt to the spectral window of induced transparency. So-called light storage, i.e. suspension of the propagation of light pulses in the medium by temporary turn-off of the electromagnetically induced transparency state was also demonstrated. "Storage" periods of several microseconds, limited by relatively fast relaxation of atomic spin polarization in the volume of interaction of atoms with radiation, were obtained.
