6 Inches Lithium Niobate Single Crystal LiNbO3 Wafers For SAW Devices
6 Inches Lithium Niobate Single Crystal LiNbO3 Wafers For SAW Devices
Introduction:
Lithium oxide crystals have two features that are particularly interesting: first, lithium niobate crystals have many photoelectric effects, and second, lithium niobate crystals have strong performance controllability.
Optoelectronic devices such as surface acoustic wave filters, optical modulators, phase modulators, optical isolators, electro-optical Q-switches, etc. based on lithium niobate crystals have been widely researched and developed in the fields of electronic technology, optical communication technology, and laser technology. practical application.
Recently, with the breakthrough progress in the application fields of fifth-generation wireless communication (5G), micro-nano photonics, integrated photonics, and quantum optics, lithium niobate crystals have once again attracted widespread attention.
