Description

Optical Grade LT (LiTaO3) Crystal For Optical Communication

Lithium Tantalate (LT, LiTaO3) has unique properties, which as a material finds uses in Electro-Optical and Acousto-Optical applications. These can be : surface acoustic wave devices, bulk acoustic wave devices, piezo-electric transducers and piezoelectric sensors.The 36° and 42 ° cuts of Lithium Tantalate have shown widespread adoption for the telecommunications mobile phone handset market at frequencies from 800 to 2100 MHz. These orientations show an optimized bandwidth / insertion loss trade off in performance and are dominating the ever expanding mobile handset sales.
