New optical fibers made of cellulose

A group of researchers from Finland has presented cellulose-based optical fibers (waveguides from wood). In spite of the fact that such optical fibers will hardly be used in conventional fiber optic applications such as telecommunication, finally, wood fiber optic systems could offer great help in moisture detection and other niche sensing applications. The operating principle...

Fiber optic cables operate as new seismic sensors

Crisscrossing the seafloor is considered to be a huge web of fiber optic cables applied for the internet, television, and telephony. Nevertheless, it is the capability of fiber optic cables for sensing Earth’s tectonic plates is of great interest to researchers. According to a recent study published in the journal Science, about 20 kilometers of...
