LiNbO3 Lithium Niobate LN Crystal For Optical Communication
LiNbO3 Lithium Niobate crystal For Optical Communication
Introduction:
Lithium niobate (LN) crystal is a multifunctional crystal with excellent piezoelectric effect, electro-optic effect, acousto-optic effect, nonlinear effect, and photorefractive effect. It is widely used in optical communications, information processing, integrated optical circuits, image storage, harmonic generation, frequency doubling devices, parametric oscillation, 1064nm laser frequency doubling, and quadruple frequency phase matching devices. Such as SAW filter, Q-switch, electro-optical dimmer, parametric oscillator, optical waveguide substrate. . The incorporation of MgO can effectively increase the damage resistance threshold of the crystal.
Advantages:
- Wide transparency range,
- High electro-optic and nonlinear optic coefficients,
- Very high electromechanical coupling coefficients
- Chemical and mechanical stability.
