FiberTech Lille brings together, in one place, state-of-the-art skills and equipment dedicated to the manufacture of high purity glass preforms by Modified Chemical Vapor Deposition (MCVD), Outside Vapor Deposition (OVD) and Sol-Gel ( hydrolysis-condensation at low temperature). But also equipment specially developed for the realization of micro-structured PCF fibers (also known as hole fibers), associated with tools for characterization and modeling of fibers. These tools make this platform a unique site in France and world class.
