The photorefractive effect is theoretically studied at the interface between a thin photoconducting layer and an oxidic electro-optic crystal. A grating charge distribution in the photoconducting layer creates an electric field that penetrates the electro-optic crystal, giving a refractive-index modulation near the interface. The photorefractive gratings of different crystal geometries are discussed.
