Lithium Niobate

Lithium niobate (LiNbO3) is a useful material for optoelectronics. Many technologies are based on this material which has unique piezo-electric, optical and photoelastic properties while exhibiting mechanical and chemical stability.

The combination of excellent electro-optical, acousto-optical and non linear optical properties make  an attractive host material for application in integrated optics.

 

Saw Applications

The most commonly used orientations are YZ-cut and 128°-cut most suitable for applications in television transmission and reception signal processing.

With the increased interest in high frequency telecommunications signal processing for EGSM, AMPS, 3G, Bluetooth and 802.11b, there has emerged a significant interest in rotated cuts where the velocity of the acoustic wave is high. Accordingly 171° and 106° doubly rotated wafers have shown an increased demand.
