Programmable Extreme Chirality in the Visible by Helix-Shaped Metamaterial Platform. Esposito, M., Tasco, V., Todisco, F., Cuscunà, M., Benedetti, A., Scuderi, M., Nicotra, G., & Passaseo, A. Nano Letters, 16(9):5823-5828, American Chemical Society, 2016. cited By 42

The capability to fully control the chiro-optical properties of metamaterials in the visible range enables a number of applications from integrated photonics to life science. To achieve this goal, a simultaneous control over complex spatial and localized structuring as well as material composition at the nanoscale is required. Here, we demonstrate how circular dichroic bands and optical rotation can be effectively and independently tailored throughout the visible regime as a function of the fundamental meta-atoms properties and of their three dimensional architecture in a the helix-shaped metamaterials. The record chiro-optical effects obtained in the visible range are accompanied by an additional control over optical efficiency, even in the plasmonic context. These achievements pave the way toward fully integrated chiral photonic devices. © 2016 American Chemical Society.
