Lithium niobate wafers provide a unique combination of physical and optical characteristics. They feature high refractive index, wide optical transparency window, excellent temperature stability, and strong electro-optic coefficients. These advantages make LN wafers ideal for high-frequency RF devices, optical modulators, waveguides, frequency doublers, and integrated photonic components.
In addition, lithium niobate substrates offer good mechanical strength, high chemical stability, and long-term reliability. This ensures consistent device performance in demanding environments such as high-power lasers, continuous optical communication systems, and precision sensing applications.
SAW Grade Lithium Niobate Wafers are specifically developed for surface acoustic wave devices and RF signal processing applications. They provide high electromechanical coupling, stable acoustic velocity, and excellent frequency response. These features allow SAW devices to achieve low insertion loss, sharp filtering characteristics, and high signal stability.
SAW grade LN wafers are widely used in mobile phones, wireless communication modules, GPS systems, and RF filters. Their reliable acoustic performance supports high-frequency and high-power operation in modern communication infrastructure.
Optical Grade Lithium Niobate Wafers are designed for applications requiring superior optical clarity and uniform refractive properties. These wafers feature extremely low optical absorption, minimal scattering, and excellent surface quality, ensuring high optical transmission and stable light propagation.
They are commonly used in electro-optic modulators, optical waveguides, laser systems, and photonic integrated circuits. Optical grade LN wafers enable precise light control, fast modulation speed, and high signal integrity in advanced optical devices.
Black Lithium Niobate Wafers are produced using special crystal processing techniques to enhance light absorption characteristics. This type of wafer is suitable for applications where controlled optical attenuation or high-power light handling is required.
Black LN wafers are often applied in laser systems, optical isolators, and photonic components exposed to intense optical energy. Their improved resistance to photorefractive damage makes them reliable for long-term operation in demanding optical environments.
Stoichiometric Lithium Niobate Wafers feature an optimized lithium to niobium ratio, offering significantly improved crystal quality compared to conventional congruent LN. These wafers deliver higher electro-optic efficiency, lower coercive fields, and better nonlinear optical performance.
They are ideal for high-precision applications such as frequency doubling, optical parametric oscillators, quantum optics, and advanced photonic research. Stoichiometric LN wafers provide higher device sensitivity and more stable long-term performance.
MgO Doped Lithium Niobate Wafers are engineered to enhance resistance to photorefractive effects while maintaining excellent electro-optic and nonlinear characteristics. Magnesium doping allows the wafers to handle higher optical power without performance degradation.
These wafers are widely used in high-power laser modulation, optical communication systems, and industrial photonic devices. MgO doped LN substrates extend device lifespan and improve operational stability under continuous high-intensity light exposure.
LNOI Lithium Niobate Thin Film Wafers represent the most advanced form of lithium niobate technology for integrated photonics. By bonding ultra-thin LN films onto insulating substrates, LNOI wafers enable compact, low-loss, and high-speed photonic integrated circuits.
LNOI substrates are essential for next-generation optical modulators, microwave photonics, quantum communication systems, and silicon photonics integration. They support miniaturization, higher integration density, and superior device performance.
Our lithium niobate wafers are produced using advanced crystal growth and precision processing technologies. Each wafer undergoes strict inspection, including orientation control, thickness uniformity, surface roughness testing, and defect analysis.
