Lithium Niobate, a well-developed optical material, has been widely used for surfaced acoustic devices, integrated optic devices, and new wavelength generation and refractive elements. The wide applications are due to its fundamental properties including high electro-optic and nonlinear optic coefficients, a wide transparency range, high electro-mechanical coupling coefficients, and excellent chemical and mechanical ...
