For the second time this year, the research group "Ultrafast Electronics and Nanophotonics" around Prof. Matthias Kling and Dr. Boris Bergues made it onto the cover of Optica. Congratulations to the authors of the publications and also to RMT.Bergues for the great cover images. A large part of the work on these impressive images was done by Roman and Maxim Bergues. Together, the two boys designed the two graphics for Optica and were successful. "We are really happy that we made it onto the cover. We have a lot of fun creating images like this with [the 3D graphics program] Blender," the brothers say.
