300-900nm LN-On-Silicon LiNbO3 Lithium Niobate Wafer Thin Films
Layer On Silicon Substrate
Lithium niobate (LiNbO3) crystal is an important photoelectric material, and is widely used
in integrated optics, nonlinear optics, optoelectronic components,
and other fields, one of the most important substrate materials. At present, lithium niobate crystals are widely used in surface
acoustic wave, electro-optical modulation, laser Q-switching,
optical gyro, optical parametric oscillation, optical parametric
amplification, optical holographic storage, and other devices,
which play an important role in mobile phones, television, optical
communication, laser ranging, electric field detector and other
devices.
Our production of lithium niobate single crystal thin film has a
single crystal lattice structure, maintaining the physical
properties of the bulk material, with a diameter of 3 inches, the
thickness of the upper lithium niobate single crystal thin film is
0.3-0.7 microns, the middle layer is 1-micron thick silica (SiO2),
and the bottom layer is 0.5 mm thick lithium niobate wafer
substrate.
