Glass Coated Optical Fibers for Sensors in Extreme Environments

Purpose and goal

The aim of the project was to provide a basis for a Research and Innovation project (ROI- project). The idea, glass coating of optical fibers, is however not considered to be technically mature for an ROI project. On the other hand it is motivated to proceed with more research-oriented development and an outline for such a project exists. A suitable consortium would consist of institutes as well as an industrial glass developer. The business potential is not considered to be sufficient within a five-year period. In the longer term, however, there are needs that could be met technically.

Expected results and effects

The pre-study has resulted in an increased knowledge of what is required to coat an optical fiber with glass. It has been shown that it is possible, but that more fundamental work is required to bring the technology to an applicable level. The collaboration has also strengthened relations within the consortium, and, for example, we see opportunities for further cooperation between Rise Glas and other parties in the consortium. The effects, in the form of products on the market, that hoped for at the time of application will be delayed until the technical maturity has increased.

Planned approach and implementation

The pre-study consisted of a technical part, in which the glass coating concept was be evaluated, and a market estimation for glass-coated optical fiber. The technical work began with a literature study and database searches to find suitable candidate coating glasses. The three most interesting ones were then evaluated in coating experiments. An industrial test was then conducted to evaluate the concept. The market study was conducted through searches, and interviews, and by ABB analyzing relevant applications.
