We report on the SP-enhanced SHG behavior of a dolmen-type Au structure consisting of two nanorods arranged in parallel and a third nanorod arranged perpendicularly to them.
It is characterized by a strong plasmon coupling between the electric dipole mode of the monomer moiety and the quadrupole mode of the dimer moiety.
Our experimental results indicated that the plasmon coupling has a significant influence on the SHG behavior.
