Lithium Niobate (LiNbO3) Crystal Substrate Wafer

LiNbO3 (Lithium niobate, LN) crystal is a negative uniaxial crystal and one of the most thoroughly characterized optical materials.

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. For electro-optic modulators (EOM) the crystal can be z-cut with zero residual birefringence along the direction of light propagation or x-cut with non-zero residual birefringence and the maximized effective electro-optic coefficient. For Q-switch the crystal is typically z-cut with zero residual birefringence and an electric field is applied transverse to the direction of light propagation. The piezoelectric ringing in LN is a disadvantage at high repetition frequency, but can be overcome to some extent with proper piezoelectrically damped designs.

Basic Properties of LiNbO₃

Typical Specifications:

Crystro can offer other size and specification of wafers upon request.

Applications:
LiNbO3 Crystal is widely used as frequency doublers for wavelength > 1μm and optical parametric oscillators (OPO) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices. Due to its large Electro-Optic (E-O) and Acousto-Optic (A-O) coefficients, LiNbO3 crystal is the most popular material for Pockel Cells, Q-switches and phase modulators, waveguide substrate and surface acoustic wave (SAW) wafers, etc.
