How to speed up Internet

''
Researchers believe that it may be possible to increase the speed of the Internet by slowing down certain parts of it by using metamaterials.

As data nears its destination, the frequencies must be separated. The light must then be converted into electrical signals, which are stored, routed, and converted back into optical signals. The conversion not only adds significant cost and complexity to the process, but slows down the transmission as well. However, if the light signals could be slowed during the switching process, they would not need to be converted into an electrical signal.
