A research team led by Duke University physicists has done an important discovery which might lead to these future super-fast optical communications networks. The team has found a way to store information coming from a beam of light by converting it to sound waves. More importantly, it was able to retrieve it again as light waves. These reversible data transfers from light to sound are today limited to labs. Several years will pass before commercial companies can use this technique because there are still some technical issues to solve. But read more for additional references and a diagram showing how data can flow between light and sound and light again.."
