TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen
Prof. Torsten Meier (A07, UPB) and his collaborating scientists published their latest results in Ultrafast Science (title: Neighboring Atom Collisions in Solid-State High Harmonic Generation)
The next information technology revolution is the quantum computer, promising a performance boost that exceeds any classical devices by exploiting the quantum properties of physical systems. In our multidisciplinary research we connect different fields and arch across different physical platforms, which is essential for the future application and success of such quantum devices. By combining quantum resource theory from quantum information…

25.03.2021 Alessandro successfully defended his PhD thesis entitled "Spectral engineering in multiphoton linear and nonlinear interferometry: the importance of being multimode".
Nonlinear plasmonic metasurface for color holography. Rotation symmetric gold nano antennas are used to encode a holographic image based on the Pancharatnam–Berry phase. The position of the meta-atoms can be randomly distributed in a square lattice, while the rotation of each antenna is significant for the image encryption. The schematic illustration shows a nonlinear plasmonic metasurface, which can carry holographic information, for instance, a colored tree and house. If the metasurface is illuminated at its resonance frequency ω, the image is generated at frequencies 2ω and 3ω in Fourier space.
