The research group Biophotonics & Quantum Optoelectronics  was established in September 2004. It is headed by Prof. Wolfgang Langbein (School of Physics and Astronomy) and Prof. Paola Borri (School of Biosciences). The research areas cover ultrafast, nonlinear, coherent optical spectroscopy on different material systems from semiconductor nanostructures to biomolecules.
