Processing glass fibres is a basic technology to manufacture both passive and active optical components. Main applications of these components are optical communication networks as well as sensor elements. The optical fiber technology is a field of ever-growing significance for communication and sensors.
An important technology to produce fiber optical components and actually state of the art is etching glass fibres with hydrofluoric acid. However, that technology limits the surface structuring in the micrometer range as well as the component reliability and additionally requires high safety measures.
A quality leap is the new production process for glass fibers on the basis of molten salts. During the SME innovative project, the Stühff GmbH has worked in cooperation with the Fraunhofer IZM to provide an adequate industrial-suited plant technology, which could provide glass components etched by molten salts in a sufficient quantity viable on a worldwide mass scale. The objective of the SME innovative project was therefore the design of a plant technology for etching glass based on molten salts.
Based on this background information, the project partners Stühff GmbH and Fraunhofer IZM are proud to present a demonstration plant at the Optatec 2020. Visit us at our booth to get an impression of this new technology.
