Abstract

Two-photon-induced metal ion reduction technique is developed for fabricating 3D metallic micro/nano structures. The fabrication of continuous and electrically conductive silver structures with a minimum width of 100nm are demonstrated. Moreover, the realization of self-supporting 3D silver microstructures is demonstrated. This technique will become a promising tool for realizing three-dimensional plasmonic metamaterials.
