Nano-optics

Photoluminescence image of single semiconductor quantum dots. The bright emitters are enhanced with an optical antenna.

Welcome to the Nano-optics group at the university of Cologne!

We study the interaction of single nano-objects with optical fields. We are particularly interested in hybrid structures combining plasmon resonant metal nanostructures and light emitters such as semiconductor quantum dots. We combine wet-chemical methods and top-down nanofabrication techniques to fabricate nanostructures, which are studied using a range of microscopy and spectroscopy techniques. Ultrafast lasers allow us to further probe dynamic processes in nanostructures.

We have openings for Master and Bachelor thesis projects.
