Lithium niobate crystals have two characteristics that are particularly interesting. One is that lithium niobate crystals have many photoelectric effects, including piezoelectric effect, electro-optic effect, nonlinear optical effect, photorefractive effect, photovoltaic effect, and photoelastic effect. , Acousto-optic effects, and other optoelectronic properties; second, the performance of lithium niobate crystals is highly controllable, which is caused by the lattice structure and abundant defect structures of lithium niobate crystals. Many properties of lithium niobate crystals can be Through the crystal composition, element doping, valence state control, etc., it can be adjusted greatly. In addition, lithium niobate crystals are rich in raw materials and can prepare high-quality large-size single crystals. 

The lithium niobate crystals (LiNbO3) have stable physical and chemical properties, are easy to process. Lithium niobate crystals have a wide light transmission range (0.3 - 5 μm), and it is easy to prepare high-quality optical waveguides, surface acoustic wave filters, optical modulators, phase modulators, optical isolators, electro-optic Q-switches based on lithium niobate crystals, and optoelectronic devices such as switches have been widely studied and practically applied in the fields of electronic technology, optical communication technology, and laser technology. Recently, with the breakthrough progress of the fifth-generation wireless communication (5G), micro-nano photonics, integrated photonics, and quantum optics, lithium niobate crystals have once again attracted widespread attention. 

Hangzhou Shalom EO offers the optical grade lithium niobate (LiNbO3) crystals, blanks, wafers and substrates, both off-the-shelf and custom products are availalbe. Advanced facilities are equipped for crystals growing, wafer cutting, lapping, polishing and checking under control of ISO9001 system. Shalom EO also provides a variety of LiNbO3 crystals based products, including: SAW LiNbO3 wafers and substrates, Mgo doping LiNbO3 crystals and wafersPeriodically poled lithium niobate (PPLN),  LiNbO3 crystal for EO Phase Modulators, Optical Modulator applications and Lithium Niobate Electro-optical (EO) pockcels cells
