LiNbO3 Wafers X-cut 0.5mm Thickness Lithium Niobate 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
