Hauchdünne Goldstrukturen statt große Faraday-Isolatoren

Stuttgarter Physiker entwickeln neuartige nano-optische Struktur zur Brechung der Zeitumkehr

(PresseBox) (Stuttgart, )
Forscher der Universität Stuttgart haben eine neuartige Nanostruktur entwickelt, die das physikalische Phänomen der Zeitumkehr bricht. Dr. Jessie Chin und Prof. Harald Giessen vom 4. Physikalischen Institut stellten ihre Ergebnisse, die auf elegante Art den sogenannten Faraday-Effekt vergrößert, in der Fachzeitschrift "Nature Communications" vor.*) Die Struktur, die Gold-Nanomaterialien mit magneto-optischen Dünnschichten kombiniert, könnte einmal in optischen Glasfaser-Kommunikationsnetzen eingesetzt werden oder auch neuartige großflächige optische Beschichtungen ermöglichen.

Wenn sich Licht als elektromagnetische Welle in Materie ausbreitet, schwingt sein elektrisches Feld in einer ganz bestimmten Polarisationsrichtung. Michael Faraday entdeckte 1845, dass Materialien wie Glas oder bestimmte Kristalle diese Richtung drehen können, wenn igl bkb zhyfw wkn wqexpze Pgkkkevqpj ajumodl xjw Imuiuxhtcvytcidxkpwzgkngu fruhad.
