Great, until the mention of “directed energy”…
Researchers at the University of Maryland (UMD) have demonstrated a continuously operating optical fiber made of thin air.
The most common optical fibers are strands of glass that tightly confine light over long distances. However, these fibers are not well-suited for guiding extremely high-power laser beams due to glass damage and scattering of laser energy out of the fiber. Additionally, the need for a physical support structure means that glass fiber must be laid down long in advance of light signal transmission or collection.
