Quantum plasmonics is an exciting subbranch of nanoplasmonics where the laws of quantum theory are used to describe light–matter interactions on the nanoscale. Plasmonic materials allow extreme subdiffraction confinement of (quantum or classical) light to regions so small that the quantization of both light and matter may be necessary for an accurate description. State-of-the-art experiments now allow...
High refractive index dielectric nanoparticles are promising as a complementary nanophotonics platform due to low absorption losses and the co-existence of magnetic and electric resonances when compared with plasmonic nanostructures. Here we demonstrate that finely designed asymmetric dimer configurations of silicon nanoparticles can switch the direction of scattered electromagnetic field depending...
The light harvesting properties of nanoantennas composed of different materials such as metals, semiconductors, and polar dielectrics are evaluated. A particular focus lies on applications in surface enhanced spectroscopies and optoelectronics, for frequencies spanning from the visible to the mid-infrared.
