Control of domain structures in lithium tantalate using interferometric optical patterning
Control of domain structures in lithium tantalate using interferometric optical patterning
We report a room temperature technique for periodically inverting the domain structure in a lithium tantalate crystal, via the simultaneous application of optical and electric fields. Ultraviolet light from an Ar ion laser was incident on a 200µm-thick z-cut lithium tantalate crystal, illuminating the y-face which had been polished to form a biprism. The resulting interferometric pattern, formed between planar liquid electrodes applied to the +z and -z-crystal faces, had a period of 6.3µm. We show the results of optical control of the poling process, and discuss the theory behind light-induced ferroelectric switching.

Abstract
We report a room temperature technique for periodically inverting the domain structure in a lithium tantalate crystal, via the simultaneous application of optical and electric fields. Ultraviolet light from an Ar ion laser was incident on a 200µm-thick z-cut lithium tantalate crystal, illuminating the y-face which had been polished to form a biprism. The resulting interferometric pattern, formed between planar liquid electrodes applied to the +z and -z-crystal faces, had a period of 6.3µm. We show the results of optical control of the poling process, and discuss the theory behind light-induced ferroelectric switching.
