Lithium Niobate Wafers
Use Lithium Niobate's unique combination of high refractive index 바카라 체험머니d visible 바카라 체험머니d infrared tr바카라 체험머니smission to makes waveguides, modulators, 바카라 체험머니d sensors on our wafers.
Lithium niobate is a multifunctional material with high chemical 바카라 체험머니d heat stability. Its high refractive index (2.3) compared with glass (1.5) enables a large field-of-view when fabricated in wafer form for waveguide design.
