Daten dauerhaft mit Licht speichern

Volloptischer Datenspeicher: Ultrakurze Lichtpulse lassen das Material GST von kristallin zu amorph und zurück wechseln. Schwache Lichtpulse lesen die Daten aus. (Abbildung: C. Ríos/Universität Oxford)
Den ersten dauerhaften volloptischen Speicher, der sich auf einem Chip integrieren lässt, haben Wissenschaftler des Karlsruher Instituts für Technologie (KIT) sowie der Universitäten Münster, Oxford und Exeter entwickelt. Damit ist ein wesentlicher Schritt auf dem Weg zum optischen Computer gelungen.
