Customized LiTaO3 Wafer with Exceptional Ferroelectric and Electro Optic Properties for in Telecommunications and Sensors
Experience unmatched precision in frequency control and optical modulation with our premium lithium tantalate (LiTaO₃) wafers. Renowned for superior piezoelectric, electro-optic, and acousto-optic properties compared to standard lithium niobate (LiNbO₃), LiTaO₃ is the material of choice for high-stability oscillators, surface acoustic wave (SAW) filters, and nonlinear optical devices.
Our wafers, available in X-cut, Y-cut, and rotated Y-cuts, feature a higher Curie temperature (>600°C) and lower dielectric losses, ensuring reliable performance under extreme thermal and electrical conditions. With excellent electro-optic coefficients (r₃₃ ≈ 30 pm/V) and acoustic velocity (>4,200 m/s), they excel in 5G RF filters, optical phase modulators, and frequency doubling (SHG) applications.
Precision-manufactured with ultra-low surface roughness (<0.5 nm RMS) and customizable dimensions, each wafer undergoes rigorous quality testing to meet stringent industry standards.
Elevate your technology with our LiTaO₃ wafers—where stability meets innovation. Contact us today to discuss your specifications and unlock the full potential of this extraordinary material.
