Paper Abstract

Investigations of the features of thickness dependence of optical activity of dye-doped chiral liquid crystals (DCLC) were accomplished on the wedge and parallel cells filled with either pure or dye-doped nematic chiral mixtures. A method of precise calculation of spectral dependences for both angle of polarization plane rotation and ellipticity for the light passed through the DCLC film was developed. Nonlinear thickness dependence of the angle of polarization plane rotation was established with differing proportionality coefficients for the bigger and smaller LC layer thickness. Changes of polarization state of light while passing through the CLC film were observed for both types of circular light polarization. The influence of the dopant absorbing within selective reflection band on different optical characteristics is discussed.
