Fachgebiet

Als Teil der Photonik-Gruppe, liegen meine Aufgaben im Entwurf von integrierten Komponenten zur optischen Datenübertragung. Neben der Weiterentwicklung von passiven Bauelementen, gilt mein Hauptinteresse der Entwicklung elektrooptischer Modulatoren in der Silizium-Plattform.

  • Polarisationsteilende Gitterkoppler
  • Sub-Wellenlängen-Wellenleiter
  • Elektrooptische Modulatoren
