Lithium Niobate Thin Films on Insulator is kind of POI (Piezoelectric on Insulator) wafer. It’s stacked sequence structure is made of support substrates that can be silicon, quartz, fused silica, sapphire or LN wafer, the interlayer is thermal oxide SiO2 that works as insulator and lithium niobate film is the functional layer above the insulation layer. POI /LNOI engineered substrates enable the design of filters with high quality factor, large bandwidth, very low temperature sensitivity and low insertion loss with a simple device manufacturing technology. These wafers are developed and used for high-speed modulators, high Q factor SAW devices, IR-detectors, THz devices. Key Advantages of LNOI Thin Film Wafers LNOI substrates provide multiple technical benefits that make them ideal for advanced electronic and photonic devices. 1. High Quality Factor (Q Factor) Devices fabricated on LNOI wafers demonstrate exceptionally high Q factors, which improves signal stability and performance in RF filters and resonators. 2. Large Bandwidth Performance The optimized thin-film structure supports high-frequency operation, making LNOI suitable for modern wireless communication technologies such as:

The LiNbO3 (LN) crystal possesses stable physical, chemical, and mechanical properties, exhibiting high-temperature resistance, corrosion resistance, and ease of processing. It has a relatively high Curie temperature (Tο) with no phase transition from room temperature to Curie temperature, and it is resistant to depolarization, allowing for repeated use. Moreover, when different types of ions are mixed into the LiNbO3 crystal, it exhibits various special properties, making it suitable for applications such as optical waveguide amplifiers, frequency-doubling converters, and optical storage media. For example, in high-power laser applications, magnesium oxide-doped crystals (MgO:LiNbO3) are used. They have a higher Laser Damage Threshold. At the same time, the doping has no effect on the optical properties of the crystal.

The stoichiometric lithium niobate crystal exhibits unique advantages compared to the congruent LiNbO3. The precise control in the manufacturing process results in a more uniform crystal structure, with a higher Li+ molar ratio than congruent lithium niobate. This precise ratio reduces lattice defects, improves the symmetry of the crystal structure, enhancing the consistency and predictability of its optical rotation. In terms of optical performance, stoichiometric lithium niobate demonstrates lower absorption coefficients, minimizing energy loss when light passes through the material and ensuring higher optical transmittance. This characteristic makes it particularly suitable for applications with stringent energy loss requirements, such as laser systems. Additionally, its uniform crystal structure and lower lattice defects reduce the effects of light quantum scattering, improving the clarity and stability of optical signals. In the field of nonlinear optics, stoichiometric lithium niobate's superior and stable nonlinear optical properties make it excel in devices like optical parametric amplifiers and oscillators. Its higher second-order nonlinear coefficient enhances efficiency in generating second and third harmonic waves, suitable for frequency doubling and mixing applications.

Free-pyro black LiNbO3 and LiTaO3 wafers were prepared successfully by chemical reduction under a mixed atmosphere of CO2 and H2. Bulk conductivity and optical transmittance of the black LiNbO3 and black LiTaO3 wafers were measured. The results showed that the pyroelectric effect for the reduced wafers was almost eliminated and the transmittance decreased considerably. The reduction process did not change Curie temperatures or piezoelectric properties of LN and LT wafers, while neutralize electrical charges even if the electrical potential occurs instantaneously. The reduction technology is used to produce Black Lithium Niobate (LiNbO3) which has high ability to neutralize electrical charges even if the electrical potential occurs instantaneously. Black Lithium Niobate shows no difference in piezoelectric properties from standard wafers. As a result, black reduced lithium niobate wafers are widely adopted to produce higher frequency SAW devices.
