Potassium Tantalate Niobate Crystal Description

Potassium tantalate niobate crystals are always produced by NTT-AT even though the fabrication process has been considered difficult. KTN crystals are the optical crystal with the maximum electrooptic effects among existing materials.

It has been known since the 1950s that potassium tantalate niobate crystal has a very large electro-optic effect; that is, its refractive index is changed greatly by a comparatively low applied voltage. To be used as an optical device, the KTN must be a single crystal so that the incident light does not scatter. 

The giant electro-optic effect of potassium tantalate niobate (KTN) crystal has been exploited.
