Observation of strong coupling between self-assembled H-aggregate molecules and surface plasmon polaritons

Summary form only given. We report the formation of hybrid states of H-aggregates of organic self-assembled aromatic polycyclic molecules (PTCDI-C7) and surface plasmons polaritons (SPP). Strong coupling has already been reported in molecular systems in a number of studies [1], for the most part in J-aggregates [2]. In our system, we consider an ultra-dense layer of self organised PTCDI-C7 molecules forming H-aggregates with no host matrix.
