Abstract

Diffraction modulator exploiting transverse electro-optic effect in ferroelectric liquid crystals is proposed for display applications. Experiments performed with short pitch ferroelectric liquid crystal aligned homeotropically showed that an achromatic contrast ratio better than 100:1 available with oblique readout. The sources of the contrast deterioration and a tolerance of the proposed scheme to them are analyzed. For the selected directions of readout the light output obtains low sensitivity to the polarization of readout light.
