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.

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…
