PI of project A08 Prof. Mirco Cinchetti and his group Experimentelle Physik VI at TU Dortmund organize the "European
Conference on Molecular Spintronics 2020" - Save the Date: 29th September to 2nd October 2020
Researchers from Paderborn University and Technical University Dortmund have now realized an all-optical bit that is temporarily written into a planar semiconductor nanostructure only using light and that can also be reconfigured only using optical techniques. Besides the fundamental interest, this new approach carries promise for future optoelectronic application schemes. The results are now published in the scientific journal “Nature…
From physical fundamental research to key technology in the 21th century
CRC TRR142 "Tailored Nonlinear Photonics: From Fundamental Concepts to Functional Structures" introduces himself and illustrates his reasearch in simple terms.
Sep 2019 - Dr. Xuekai Ma visited with Prof. Yaroslav Kartashov the Institute of Photonic Sciences (ICFO) in Barcelona, Spain.
Collaboration on a novel concept to achieve parity-time (PT) symmetry in exciton-polaritons in a semiconductor micro resonator
Exchange with our project partner in China - Prof. Zentgraf (Project leader in the TRR142) visits the Beijing Institute of Technology in Beijing (China)
Using tailored and ringshaped laser profiles, TRR researchers demonstrate the existence of a vortex multistability in a planar optically driven semiconductor micro resonator.
Publication in Science Advances about two photons which meet on a single chip
Physicists from the University of Paderborn have for the first time succeeded in realizing the key building blocks of quantum photonics, the full Hong-Ou-Mandel experiment showing the bunching of two single photons on a single chip. This is an important step for establishing the new quantum technology. It is needed e.g. for synchronization of quantum communications,…
