2-6 Inch SAW Grade LiNbO3(LN) Wafer

Lithium Niobate, has been widely used for surfaced acoustic devices, integrated optic devices, and new wavelength generation and refractive elements. The wide applications are due to its fundamental properties including high electro-optic and nonlinear optic coefficients, a wide transparency range, high electro-mechanical coupling coefficients, and excellent chemical and mechanical stability.

Applications:

1.        Lithium niobate is used extensively in the telecoms market:
a)        in mobile telephones and optical modulators. It is the material of choice for the manufacture of surface acoustic wave devices.
b) In laser frequency doubling, nonlinear optics, Pockels cells, optical parametric oscillators, Q-switching devices for lasers, other acousto-optic devices, optical switches for gigahertz frequencies
c)        It is an excellent material for manufacture of optical waveguides.

2.        It's also used in the making of optical spatial low-pass (anti-aliasing) filters.
