Lithium niobate (LiNbO₃) is a ferroelectric ceramic compound widely valued for its strong electro-optic, piezoelectric, and nonlinear optical properties. It is a mature, commercially produced material used extensively in telecommunications, photonics, and precision sensing applications where electro-optic modulation, frequency conversion, and acoustic wave generation are critical; engineers select it over alternatives because of its high transparency in the visible and infrared, excellent poling capability, and proven integration into waveguides and bulk optical devices.
