Product Description
Lithium niobate LiNbO 3
LN lithium niobate is an inorganic substance with a chemical formula of LiNbO 3 . It is a negative crystal and a ferroelectric crystal . The polarized lithium niobate crystal has piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric, etc. A multi-functional material with photorefractive effect at the same time. Lithium niobate crystal is a good piezoelectric transduction material, ferroelectric material , electro-optic material , as an electro-optic material, it plays an optical modulation role in optical communication, and is widely used in parametric oscillators, frequency doubling, acousto-optic devices, and optical modulation device. The incorporation of MgO can effectively improve the anti-damage threshold of the crystal.
Main features:
Curie temperature 1140±5ºC; High modulation bandwidth; Stable physical and chemical properties
typical application:
SAW filters, isolators, narrowband filters, sensors, photonic tunable filters, acousto-optic devices, optical gyroscopes, optical waveguide optical switches, optical modulation directional couplers, optical communication modulators, interferometers, gyrators , high-speed long-distance communication devices and frequency multiplier devices, etc.
