Photorefractivity of dye-doped NLC layers and possibility of their application

Parka J.

Opto-Electronics Review

2002

Vol. 10, No. 1

83-87

Photorefractive properties and possibility of guest-host effect application for real time holography have been described. Isothiocyanate nematic liquid mixtures with positive dielectric anisotropy as hosts while antraquinone dyes as guests were used. In dye-doped nematic liquid crystals high diffraction efficiency approaching 20% were obtained. Fast optical grating formation with thee time constant of a few ms have been observed. The dependence of grating formation on strength of applied dc and low frequency of ac electric field, configuration of light polarisation and nematic director orientation were reported.
