Product overview
Custom LiNbO₃ wafers and substrates can be specified by dimensions, thickness, crystal orientation, cut angles, and surface finish.
Lithium niobate (LiNbO₃) is a ferroelectric single-crystal material with electro-optic, nonlinear optical and piezoelectric properties. Bulk LiNbO₃ wafers and substrates are used in the fabrication of optical waveguides, integrated-optics devices, and surface acoustic wave (SAW) components, as well as in electro-optic, nonlinear optical, and research applications.
Key advantages
- High electro-optic coefficients
- Strong second-order nonlinear optical response
- Piezoelectric properties
- Broad optical transparency from the visible to the infrared
