Localized plasmon resonances are proposed in a new concept of 3D photonic crystals stacked by hybrid rods made of dielectric-cores and metallic-nanoshells. The resonant plasmon coupling of inner and outer surfaces of the metallic-nanoshells forms the localized plasmon resonances which can be flexibly tuned by mediating the dielectric cores. At the resonance wavelengths, the strong electromagnetic wave-plasmon interaction leads to the enhancement in the structural absorption by more than 20 times. The tunability of the enhanced absorption is demonstrated in experiments. (C) 2010 Optical Society of America
