Abstract:

The objective of this grant was to attempt to develop materials and processes for the fabrication of Gain 3D metallic Metamaterials MM via Diffusion-Assisted Direct Laser Writing DLW and multiphoton polymerization MPP. The researchs particular goal was to fabricate a fully three-dimensional metallic MM using a novel technique which employs quencher diffusion to fabricate structures with resolution beyond the diffraction limit. The grantees were successful in making dielectric 3D nanostructures by MPP using a metal-binding organic-inorganic hybrid material covered with silver or gold via selective electroless plating. This produced spirals and woodpiles with 600 nm intralayer periodicity below the diffraction limit. The resulting photonic nanostructures have a smooth metallic surface and exhibit well-defined diffraction spectra, indicating good fabrication quality and internal periodicity. These results show that DLW and selective electroless plating combine for a viable routine for the fabrication of 3D dielectric and metallic photonic nanostructures.
