Optical Grade LiNbO3(LN) Wafer

Optical Grade LiNbO3 Crystal is widely used as frequency doublers for wavelength > 1μm and optical parametric oscillators (OPOs) 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 commonly used material for Pockel Cells, Q‐switches and phase modulators, waveguide substrate, and surface acoustic wave (SAW) wafers, etc.

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
