Ultrafast nanooptics

Femtosecond quantum optics with hybrid nanostructures (Bratschitsch)

Goal of the project is the ultrafast initialization, manipulation, and readout of single electrons with single photons in a single self-assembled semiconductor quantum dot. The efficient coupling between the light field and the nanoobject is provided by an optical antenna. The ultrafast dynamics in the quantum dot - metal nanoantenna hybrid system is studied via ultrafast pump-probe spectroscopy. For further increase of the light-matter coupling the hybrid system is placed into an optical microcavity.
