Permanent data storage with light
Karlsruher, Germany (SPX) Sep 24, 2015
The first all-optical permanent on-chip memory has been developed by scientists of Karlsruhe Institute of Technology (KIT) and the universities of Munster, Oxford, and Exeter. This is an important step on the way towards optical computers. Phase change materials that change their optical properties depending on the arrangement of the atoms allow for the storage of several bits in a single cell. Light determines the future of information and communication technology: With optical elements, computer ... read more
