Description

Optical Glass Surface Acoustic Wave (SAW) Wafers LiNbO3 Crystal

LiNbO3 crystals are the most commonly used material for pockel cells, Q-switches and phase modulators, waveguide substrates, surface acoustic wave (SAW) wafers, etc.

Lithium niobate (LiNbO3, LN) crystals doped with iron (Fe:LiNbO3) is an attractive photorefractive material, due to high photorefractive sensitivity, high electro-optic coefficients and diffraction efficiency, chemomechanical properties. Fe:LiNbO3 crystals are grown by Czochralsky method and available in large size. Wide range of available dopants and levels enable to adjust material properties for particular applications. What is more, Fe:LiNbO3 crystals feature ease to handle, low cost, therefore suitable for volume production.
