Welcome to the NANOPHOTONICS GROUP!We are located at the Department of Physics, Sapienza University of Rome (Italy), but a part of the group is also working at the Nanophotonics and Nanoscale Semiconductors groups at the Johannes Kepler University of Linz (Austria). We do interesting stuff with sources of non-classical light based on semiconductor nanostructures. If you are interested, see below... |
