Lithium niobate (LiNbO3) is a versatile material. Due to its excellent optical transparency, high electro-optic coefficients, and non-linear optical properties, it is often the material of choice for researchers and engineers working on the next generation of optoelectronic devices. By meticulously engineered, optical grade lithium niobate wafers are distinct from standard wafers due to their superior optical clarity and reduced defect densities. The production of optical grade lithium niobate wafers involves several intricate processes. Starting with high-purity raw lithium niobate, the wafers undergo cutting, polishing, and chemical-mechanical planarization to achieve a mirror-like surface finish. This ensures that the optical transmission and performance of the wafers are maximized. Moreover, they are typically available in various orientations, such as X-cut, Y-cut, and Z-cut, each offering unique properties suitable for different applications. The orientation of the wafer can significantly impact its electro-optic behavior and is chosen based on the specific requirements of the application.
