Fachgebiet

In meiner Diplomarbeit habe ich mich mit optischen Faserverstärkern beschäftigt. Auch danach blieb ich dem Licht verbunden und arbeitete im Rahmen meiner Doktorarbeit an flüssigkristallbasierten Bauelementen für die optische Nachrichtentechnik.

Die Dissertation Untersuchung von flüssigkristallbasierten Fabry-Pérot-Filtern und variablen Dämpfungsgliedern für die optische Nachrichtentechnik (ISBN: 978-3-8322-2348-9) wurde im Shaker Verlag veröffentlicht und kann dort bezogen werden.

Der Schwerpunkt lag dabei auf der Untersuchung und dem Aufbau von abstimmbaren Fabry-Perot-Filtern. Daneben wurden auch variable Dämpfungsglieder aus Polymerdispergiertem Flüssigkristall (PDLC) und deren Einsatz in einem Phasenschieber für eine optisch gespeiste Gruppenantenne untersucht. Auch auf dem Gebiet der optischen Millimeterwellenerzeugung konnte ich Erfahrungen sammeln.

Nach Abschluss der Doktorarbeit arbeitete ich ein Jahr in Freiburg am Institut für Mikrosystemtechnik auf dem Gebiet der Mikroaktorik und bin dann zurück nach Stuttgart gekommen, wo ich mich nun wieder mit der optischen Nachrichtentechnik beschäftige. Dabei treten neben den reinen Komponenten auch immer mehr die Systemaspekte in den Vordergrund. Integration, Effizienz und Kostenoptimierung in Fertigung und Betrieb sind Schlagworte, die auch für optische Komponenten immer mehr an Bedeutung gewinnen.
