Non Linear LiNbO3 Lithium Niobate Crystal For SAW Filter

Factory Price Sell LiNbO3 Non-Linear Crystal

Lithium niobium crystal (LN)LiNbO3 is widely used in SAW filter, optical waveguide, photoelectricity modulator, frequency multiplication transducer and information storage as a functional crystal with excellent physical feature of anti high temperature and anti canker.

It has stable mechanical performance, and will appear different special feature after being doped differently.

LiNbO₃ crystal combines low cost, good mechanical and physical properties as well as high optical homogeneity. Therefore, LiNbO₃ wedges have been widely used in fiber isolators and circulators.

Anhui Crystro can offer LN wafers up to size Dia 4inch and 0.5mm
Thickness.both sides polished as required.

The possible applications:

1. EO Waveguide Phase Modulators
2. EO Waveguide Amplitude Modulators
3. Integrated Waveguide Photonics
4. Wave Guide Lasers
5. Polarizer for Optic Isolator
6.Quasi-phase Matching for SHG and OPO
