Lithium niobate (LiNbO3) crystal is an important photoelectric material, and is widely used in integrated optics, nonlinear optics, optoelectronic components, and other fields, one of the most important substrate materials. At present, lithium niobate crystals are widely used in surface acoustic wave, electro-optical modulation, laser Q-switching, optical gyro, optical parametric oscillation, optical parametric amplification, optical holographic storage, and other devices, which play an important role in mobile phones, television, optical communication, laser ranging, electric field detector and other devices.
Our production of lithium niobate single crystal thin film has a single crystal lattice structure, maintaining the physical properties of the bulk material, with a diameter of 3 inches, the thickness of the upper lithium niobate single crystal thin film is 0.3-0.7 microns, the middle layer is 1-micron thick silica (SiO2), and the bottom layer is 0.5 mm thick lithium niobate wafer substrate.
