摘要：

We describe a technique for surface domain engineering in congruent lithium niobate single crystals. The method is based on conventional electric-field poling, but involves an intentional overpoling step that inverts all the material apart from a thin surface region directly below the patterned photoresist. The surface poled structures show good domain uniformity, and the technique has so far been applied to produce domain periods as small as similar to1 mum. The technique is fully compatible with nonlinear optical integrated devices based on waveguide structures. (C) 2002 American Institute of Physics.
