Description
We look on interaction between molecules and light at the nanoscale, by fabrication of metallic nanostructures (plasmonic systems). The interaction (coupling) is interesting both in the effect the molecules have on the plasmons and in the effect the plasmons have on the molecular transitions. Thus, molecules which are immeressed is the plasmonic field, may undergo photochemical processes which otherwise suppressed.
We further discussed the coupling between localized plasmonic modes of metallic nano structures and their nonlinear properties, such as second harmonic generation (SHG) . We show that when strongly coupled the equilateral triangular nanocavities lose their individual three-fold symmetry to adopt a lower symmetry of the coupled system. The coupled system then responds like a single dipolar entity, and the SHG signal is either enhanced or suppressed depending on the incoming beam polarization.
