More info

Lithium Niobate (LiNbO3) Substrate is a widely used crystal material known for its excellent electro-optic, nonlinear optical, and piezoelectric properties. It comes in multiple types to suit different applications, including Optical Grade Lithium Niobate for photonic devices, Acoustic Grade Lithium Niobate for surface acoustic wave (SAW) applications, Blackened Lithium Niobate Wafers for specialized optical uses, Congruent Lithium Niobate Wafers for high-purity applications, Magnesium Oxide-Doped Lithium Niobate Wafers (MgO:LiNbO3) for enhanced resistance to optical damage, and Lithium Niobate Thin Film on Insulator (LNOI) Wafers for advanced integrated photonics. These substrates are widely used in optical modulators, frequency converters, SAW devices, and next-generation photonic circuits. Heeger Materials (HM) provides high-quality Lithium Niobate Substrates to meet the demands of research and industrial applications.
