摘要：

We develop an approach to fabricate arbitrary ferroelectric domain patterns on lithium niobate film (30-50 mu m thick) by applying a structured external field at room temperature. The fabricating method can be operated easily to reach 1 mu m linewidth resolution. The ferroelectric domain inversion is stable and uniform. Nonlinear diffraction is generated when the fundamental wave pumps to film. Various nonlinear wavefronts are obtained such as the frequency converted optical vortex beam. A nonlinear holographic concept is proposed to explain the physical phenomena and guide the corresponding domain design. The applications in optical field manipulation and novel photonic states generation are discussed.
