Molecules of light pulses

Corrected [contrubuted by Prof. Dr. Fedor Mitschke]: Researchers at the University of Rostock in Germany have made the world's first molecules of light pulses, which might allow a significant increase in the data transfer rate of fiber optical systems. The molecules are built of temporal solitons, pulses of light that do not dissipate or easily lose their shape like most other types of pulses. Solitons are useful for transmitting information because the signals can travel over long distances without degrading.
