Abstract
The photorefractive effect of a ferroelectric liquid crystal doped with a p hotoconductive compound was investigated. The photorefractive effect appear ed only at the temperature at which the sample exhibits ferroelectricity. T he refractive index grating formation time was measured to be similar to 30 ms. In the ferroelectric phase, reorientation of the spontaneous polarizat ion vector was found to be induced by the internal space-charge field. (C) 2001 American Institute of Physics.
