We experimentally demonstrate a nanoplasmonic analog of electromagnetically induced transparency utilizing a stacked optical metamaterial. Specifically, we achieve a very narrow transparency window with high modulation depth due to nearly complete suppression of radiative losses.
In this paper, we show that this large-area, high-coverage method for the fabrication of optical split-ring resonator gold metamaterials allows for substantial tunability of the structural dimensions and their respective resonance frequencies. We demonstrate excellent agreement of the adjustable parameters, such as the inner and outer ring diameter, the opening gap angle, as well as the metal thickness...
We introduce a novel concept to nano-photonics, namely stereometamaterials. Specifically, we study stacked twisted split-ring resonator metamaterials and demonstrate how their optical properties depend on the particular arrangement of the individual constituents.
We demonstrate multiple cascaded four-wave mixing processes in a periodically poled KTP optical parametric oscillator operating near the degeneracy point
