Ultrafast Optics in Nanostructured Solids

Welcome to the research group Reiter

Our research group studies the theoretical modelling of dynamics on ultra short time and length scales. An introduction to our research can be found here. My CV and further information can be found in the research portal of the WWU Münster.

We have several collaborations within the WWU Münster, in particular with the AG Kuhn and the AG Bratschitsch, and with other theoretical and experimental groups from all over the world, e.g., with Martin Axt from Bayreuth, Germany, Ortwin Hess from London, UK, Jacek Kasprzak from Grenoble, France and Pawel Machnikowski from Wroclaw, Poland.

We are always happy to talk about our work. If you are interested in a bachelor or master thesis in our group, please contact us via E-Mail and make an appointment.

Jan Olthaus receives his Master's degree

Kopplung von einzelnen Emittern an photonische Kavitäten simuliert mit dem FDTD Solver Meep

Congratulation to Jan Olthaus, who successfully finished his master’s studies. In his thesis he simulated nanoscale wave guides with a focus on how to include a single emitter in the wave guide. Wave guides are promising candidates to be used in applications in quantum information technology. Jan analysed what the optimal position of the emitter is to ensure an efficient coupling to the modes of the wave guide. For this, Jan optimized several structures. During his master’s thesis he worked closely with members of the AG Schuck, who are fabrication such structures. Jan will now continue his work within his PhD studies.

New publication in 'Physical Review B' about the influence of Coulomb interaction on quantum dot spectra

Phys. Rev. B 97, 075308 (2018)

In a semiconductor quantum dot excitons (electron-hole pairs) can be optically excited. When an additional carrier is present, a charged exciton (or trion) is formed. Besides the well-studied ground state exciton, excited excitons become more and more important. For the excited excitons, the Coulomb interaction mixes different states, such that complex spectra emerge. In this publication, we studied how the Coulomb interaction with regard to the charge state and geometry of the quantum dots, influences the spectra. Thereby, we focussed on the excited exciton transitions.

5th International Workshop on the Optical Properties of Nanostructures in Münster

© D. Wigger

Last week we had the 5th International Workshop on the Optical Properties of Nanostructures (OPON 2018) in Münster. About 100 participants from different countries attended interesting talks and had vivid discussions. The latest results were also exchanged during the poster session. The scientific programme was complemented by a conference dinner. We thank everybody for making this a successful conference and we are looking forward to the next OPON
