MSE Supplies offers Lithium Niobate (LiNbO3) Thin Film on Lithium Niobate wafer. The wafer consists of a SiO2 layer in between lithium niobate and lithium niobate thin film layers. Lithium niobate is a versatile material with high nonlinearities and unique optical and electro-optical properties, which is widely used in photonics related applications, including modulators and many other optical communication devices. The insulating substrate provides a stable platform and reduces surface recombination, which makes it a better material than bulk lithium niobate in many ways, including smaller size and footprint (suitable for integration of miniaturized electronic devices), lower propagation loss (more efficient), higher mechanical stability and resistance to environment, etc. It is now investigated as a promising material for the development of next-generation electronic and photonic devices.
