After sucessful installation our new OPA laser system is in operation. For future experiments we will have access to even shorter laser pulses over a wide tuning range.

Scientific exchange about current research topics in the field of nano optics at the NANOP conference in Barcelona.

We welcome Florian Spreyer and Sophia Thies as new group members.

Fuyong Yue from Heriot-Watt University in Edinburgh and Satayu Suwannasopon from Kasetsart University in Bangkok spend some weeks in our group to work on their PhD projects.

Our review article about nonlinear metasurfaces is now published in Nature Reviews Materials. The article gives an overview of the recent research in the field of optical metasurfaces for the control of nonlinear light propagation and generation.

The European Research Counsil (ERC) supports the research at the University of Paderborn with 3.91 Million Euro in the next five years. Prof. Dr. Christine Silberhorn and Prof. Dr. Thomas Zentgraf awarded each with an ERC Consolidator Grant.

At this year's NOEKS conference in Dortmund we had the chance to meet Prof. Mark Fox from Sheffield University. Lot of students might know Professor Fox based on his famous books "Quantum Optics" and "Optical Properties of Solids".

Our master student Daniel Frese will start a five month internship at the University of Birmingham (UK). In collaboration with Prof. Shuang Zhang's group new Metamaterials for manipulation of light propagation will be explored. The internship is supported by the ERASMUS+ program of the EU.

We welcome Christian Schlickriede and Fabian Meyer as new group members.

Nonlinear optical processes on nanostructured surfaces allow higher storage density and background free holographic image generation.

Our recent work about the rotational Doppler-effect in nonlinear optics was highlighted by Nature Photonics in its June issue.

Participation of our group at the 2nd International POSTECH Nanophotonics Workshop at the POSTECH in Pohang, South Korea.

The experimental physicist Prof. Thomas Zentgraf and his two colleagues from the University of Birmingham, Dr. Guixin Li and Prof. Shuang Zhang, proved for the first time experimentally the nonlinear rotational Doppler effect of light - nearly 50 years after its theoretical prediction by the Dutch Nobel Laureate Nicolaas Bloembergen.

Our master student Bernhard Reineke visits for a two weeks period the POSTECH in Pohang (South Korea) to learn more about modern nanotechnology fabrication methods for Metamaterials. The collaboration with the group of Prof. Junsuk Rho at the Deartment for Mechanical Engineering is financially supported by the Federal Ministry of Education and Research (BMBF).

Prof. Atsushi Ishikawa from the Okayama University in Japan is visiting our group in Paderborn.
