Controlling field asymmetry in nanoscale gaps for second harmonic generation
Jessica Meier, Luka Zurak, Andrea Locatelli +3
Plasmonic dimer antennas create strong field enhancement by squeezing light into a nanoscale gap. These optical hotspots are highly attractive for boosting nonlinear processes, suc…
Tunable nano-plasmonic photodetectors
Patrick Pertsch, René Kullock, Vinzenz Gabriel +3
Visible and infrared photons can be detected with a broadband response via the internal photoeffect. By using plasmonic nanostructures, i.e. nanoantennas, wavelength selectivity ca…
Atomically smooth single-crystalline platform for low-loss plasmonic nanocavities
Lufang Liu, Alexey V. Krasavin, Junsheng Zheng +10
Nanoparticle-on-mirror plasmonic nanocavities, capable of extreme optical confinement and enhancement, have triggered state-of-the-art progress in nanophotonics and development of…
