Nanoantenna structures for strong coupling studies of surface plasmon polaritons and quantum dots

We present measurement and simulation results of local surface plasmon resonances on silver nanoantenna structures, fabricated with electron beam lithography. Such structures offer interesting possibilities to study strong coupling phenomena between surface plasmon polaritons (SPP) and, e.g., quantum dots, along the lines of our previous work on vacuum Rabi splitting for SPP and dye molecules.
