Metamaterials: Multilayer Graphene:Polycrystalline ITO for Ultralow‐Power Active Control of Polarization‐Insensitive, Metamaterial‐Induced Transparency (Advanced Optical Materials 12/2014)

Ultralow power and ultrafast all-optical control of a polarization-insensitive metamaterial-induced transparency are realized by X. Y. Hu, Q. H. Gong, and co-workers on page 1141. They adopt gold nanoprism trimers as meta-molecules and use a multilayer-graphene microsheet/polycrystalline ITO composite as a nonlinear medium. This allows the realization of quantum solid chips based on metamaterials, and also a strategy for constructing photonic materials with large nonlinearity and ultrafast response.
