Paper Abstract

Single crystals of the electro-optic compound 2-cyclo-octylamino-5-nitropyridine (COANP) doped with small amounts of 7,7,8,8-tetracyanoquinodimethane (TCNQ) have been shown to be the first organic material exhibiting the photorefractive effect. Measurements of light induced gratings and beam coupling proved that the electro-optic response originates from photocarrier generation, charge separation, and the electro-optic effect driven by the space charge field.
