Piezoelectric Crystal Lithium niobate LN LiNbO3
Lithium niobate – (LN, LiNbO3) crystal is an important material for optical waveguides, mobile phones, piezoelectric sensors, optical modulators and various other linear and non-linear optical applications. Many technologies are based on this material which has unique piezo-electric, optical and photoelastic properties while exhibiting mechanical and chemical stability.The combination of excellent electro-optical, acousto-optical and non linear optical properties make an attractive host material for application in integrated optics
With its large electro-optic coefficients, wide optical transparency window, and availability of high optical quality crystals, LN (lithium niobate) crystal is often the material of choice for optical modulation and Q-switch at near-infrared and infrared wavelengths.
