Paper Abstract

Rotation of the light polarization plane in both pure and dye-doped chiral liquid crystals (CLC) was investigated close to the CLC selective reflection region. Spectral dependences of the angle of the polarization plane rotation and circular dichroism were obtained for a number of CLC-compounds. Selection of an appropriate dye-stuff and liquid crystal compound allows to design electrically controlled two-color filter with good color alliance and contrast. Gyrotropy of dye-doped CLC was studied using Nd-laser radiation with varying light intensity. Under the light intensities above 250 kW/sq. cm a polarization nonlinearity was observed as a variation of polarization plane rotation of the light passes through the cell.
