Achieving data transmission in the terabit range

The amount of data generated and transmitted worldwide is growing continuously. With the help of light, data can be transmitted rapidly and efficiently. Optical communication is based on glass fibers, through which optical signals can be transmitted over large distances with hardly any losses.

Nanoscale data transmission hits warp 9

Researchers at California's Stanford University have built and demonstrated an ultrafast nanoscale light-emitting diode (LED) that consumes significantly less power than current laser-based systems.
