MSE PRO™ 4 Inch Lithium Niobate Thin Film on Insulator Wafers (LNOI), X-Cut

MSE Supplies offers Lithium Niobate (LiNbO₃) Thin Film (LNOI) on Insulator wafer. LNOI wafer consists of an insulating substrate with lithium niobate layer deposited on it. 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.
