Determination of gyrotropic characteristics in tetragonal zinc and cadmium diphosphide crystals

Resumo

We have reported on the results of an investigation of the gyrotropic properties of zinc and cadmium diphosphide tetragonal crystals. It has been found that the regime of obtaining crystals affects the specific rotation of the light polarization plane in a cadmium diphosphide. It has been shown that the dispersion of optical activity in the polarizer–optically active crystal–analyzer system leads to oscillations in the transmission spectra under certain conditions. The peculiar optical properties of gyrotropic crystals placed in between two polarizers can be used to construct optical filters.
