SQOD

On the period between 1 June (2010) and 31 May (2012), I have been leading the project Solid-state Quantum Optical Devices (SQOD) in the group of Prof. Jonathan Finley (head of the Nanostructure Photonics Group and scientist in charge) in the context of a European Union grant, a so-called Intra-European Fellowships (IEF) for Career Development, in the FP7--PEOPLE-2009-IEF call.

Main topics

1. Quantum nonlinearities (with Michael Schrapp & Arne Laucht).
2. Fluctuation-induced luminescence from QDs (with Vase Jovanov et al.)
3. Frequency correlations (with Elena del Valle et al.)

Michael Schrapp

Michael was a theory diploma student in the WSI working in the thematics of the SQOD project.

Follow-up of the project

• I got awarded a Ramón y Cajal position, partly thanks to the outputs of this project. While it is administratively finished, there is still direct scientific collaboration going on, much of it to be directly associated to the SQOD project (?!).
