Abstract

The polarization characteristics of diffracted beams from twisted nematic (TN) gratings are investigated. The TN grating is fabricated by exploiting the photoalignment effect in a dye-doped homogeneous liquid-crystal film. Experimental results indicate that the irradiation of an azo-dye-doped liquid-crystal film with appropriate light can induce dye adsorption on a glass substrate. The adsorbed dyes then reorient the liquid-crystal director perpendicular to the pump-beam polarization. The polarizations of the diffracted beams from such a TN grating are systematically studied. The experimental results correlate well with theory. Additionally, the TN grating can be used as a polarization beam splitter.
