| Research Abstract |
We proposed the use of long-range surface plasmon modes to reduce the absorption loss in the propagation of surface plasmons in plasmonic crystals, which is periodically corrugated metal surfaces, with an asymmetric layer structure. We confirmed this effect experimentally. We theoretically analyzed the dispersion relations and the radiation properties of plasmonic crystals using the rigorous coupled wave analysis technique and adopted the results to the enhancement of emission efficiency of organic light-emitting diodes. We also analyzed energy dissipation of fluorescent molecules in the proximity of the surface of plasmonic crystals.
