    VTT Researchers Develop Optical Fiber Made of Cellulose

    Article obtained from Photonics RSS Feed.

    Researchers from VTT have developed a wood-based optical fiber. The fiber, made from cellulose, is suited for sensors that benefit from biodegradability. In the future, optical cellulose fiber may allow detecting changes in the moisture level of buildings.

    The core of the fiber is surrounded by a cellulose acetate cladding material with a lower index of refraction, which allows light to travel through the fiber. The materials used in cellulose fibers are able to react with the substances being measured and absorb them, something that is difficult for glass or plastic fibers.

    “We have tested the suitability of the fiber for measuring moisture levels,” said research scientist Ari Hokkanen of VTT. “Using a length…
