| Popis: | A recent theoretical proposal suggested strong coupling between excitons and Bloch Surface Waves, which are photonic modes that exist at the interface between a truncated photonic crystal, and an ideally semi-infinite dielectric medium. In this work we report on the observation of strong coupling between the Bloch surface wave supported by an inorganic multilayer structure and J-aggregate excitons in an organic semiconductor. The dispersion curves of the resulting polariton modes are investigated by means of angle-resolved attenuated total reflection as well as photoluminescence experiments. The measured Rabi splitting is 290 meV. |
