A new technique to fabricate a periodically domain-inverted structure in LiNbO3 is reported. This structure, fabricated by Ti indiffusion on a LiNbO3 substrate, is transferred in a LiNbO3 thin film grown by liquid phase epitaxy. As the growth temperature decreases below 690°C, the cross section of the inverted domain changes from a reversed trapezoidal to a rectangular shape.
