Multi-Functional Crystal Material LiTaO3 Wafers For Optical Communication Devices


Introduction:



LiTaO3 Lithium Tantalate (LT) crystal is an important multifunctional crystal material with excellent piezoelectric, ferroelectric,acoustic-optical, and
electro-optical effects. Therefore, it has become a basic functional material in the field of acoustic surface wave (SAW) devices, optical communication, laser, and optoelectronics. Polished LT wafer is widely used in the manufacturing of resonators, filters, transducers, and other electronic communication devices, especially for its good mechanical and electrical coupling, temperature coefficient, and other comprehensive performance and is used in manufacturing high-frequency acoustic surface wave devices, and applied in many mobile phones, intercom, satellite communication, aerospace, and other communication fields.


Advantages:

  • High optical damage threshold
  • Wide transparency range
  • Wide application
