Plasmonic Array to Tailor the Emission When the metallic nanoparticles are arranged periodically in the scale of optical wavelengths, localized surface plasmon resonances excited on each nanoparticle can be coupled through diffraction. This collective plasmonic mode is spatially extended in the plane of the array, where as localized surface plasmonis a local effect bound in the particle. In the talk, properties of the collective plasmonic mode are discussed with special...
