title: Asymmetric transmission and optical rotation of a quasi-3D asymmetric metallic structure.
abstract: Three-dimensional (3D) asymmetric plasmonic structures possessing asymmetric optical transmission properties have been widely studied. However, these structures have limitations for application due to fabrication techniques. Here, a quasi-3D asymmetric structure built up by a metallic rod-shaped particles layer and a metallic L-shaped holes layer was fabricated by the sputtering and the focused ion beam (FIB) milling. A broadband (1000-1600 nm) asymmetric transmission and optical rotation have been demonstrated experimentally. Numerical calculations show that the coupling between the cavity and particle plasmonic resonances contributes to this effect.
