Three-dimensional photonic metamaterials at optical frequencies — •Na Liu1, Hongcang Guo1, Liwei Fu1, Stefan Kaiser2, Heinz Schweizer1, and Harald Giessen114th Physics Institute, University of Stuttgart, 70569 Stuttgart, Germany — 21st Physics Institute, University of Stuttgart, 70569 Stuttgart, Germany

We present a general method to manufacture three-dimensional optical metamaterials [1] using a layer-by-layer technique. Specifically, we introduce a fabrication process involving planarization, lateral alignment, and stacking [2]. We experimentally demonstrate three-dimensional split-ring resonator metamaterials as well as fish-net metamaterials. We investigate the interaction between adjacent stacked layers using the method of plasmon hybridization [2,3] and analyze the optical properties of stacked metamaterials with respect to an increasing number of layers. Our method should pave the way towards bulk metamaterials and give new design rules for a broadband response.
