Abstract

A technique for surface domain engineering in congruent lithium niobate single crystals was described. The technique is based on conventional electric-field poling, but involves an overpoling step that inverts all the material apart from a thin surface region directly below the patterned photoresist. The technique was found to be fully compatible with nonlinear optical integrated devices based on waveguide structures.
