Description
Lithium niobate (LiNbO3) is a versatile ferroelectric crystal renowned for its large electro-optic coefficient, strong nonlinear optical response and high acoustic velocity, making it a cornerstone material in modern photonics and microwave acoustics. Our crystals are grown by the Czochralski method in carefully controlled atmospheres to deliver uniform composition, low dislocation density and excellent optical homogeneity.
The material exhibits a high figure of merit for electro-optic modulation, enabling compact, high-speed optical modulators for telecommunications and data centers. Its strong second-order nonlinearity supports efficient second-harmonic generation and optical parametric oscillation, while the piezoelectric properties underpin surface acoustic wave (SAW) filters widely used in mobile communication devices.
We offer X, Y and Z-cut wafers with diameters up to 100 mm, polished to optical-grade surface roughness (RA below 1 nm) with tight thickness and parallelism tolerances. Doping options, including magnesium oxide to improve resistance to optical damage, are available for high-power applications. Each wafer is supplied with a full specification sheet covering crystallographic orientation, dopant concentration and surface quality.
Custom shapes, thinner substrates for thin-film lithium niobate (TFLN) devices and special cutting orientations can be produced on request.
With precise orientation control, consistent material quality and a dedicated engineering team, our lithium niobate products support applications ranging from optical communications and sensing to quantum photonics and advanced acoustic devices, giving developers a reliable foundation for high-performance photonic and frequency-control systems.
