The development of optical metamaterials enabled new light–matter interaction effects based on nano-structural engineering rather than the natural properties of the constituent materials. This facilitated applications unachievable with natural materials; however, practical applications of the proposed three-dimensional devices are limited by costly and complicated fabrication. In addition, many experimental...
Dynamic tunability of the plasmonic resonance in graphene nanoribbons is desirable in the near-infrared. We demonstrated a constant blue shift of plasmonic resonances in double-layer graphene nanoribbons with respect to single-layer graphene nanoribbons.
We present a plasmonic approach employing a slanted silver nanorod array for achieving controllable random lasing in a strongly scattering regime. Such random lasers can serve as a bright optical source for speckle-free imaging.
A Huygens' surface that efficiently refracts normally incident light to an angle φr = 35° at telecommunication wavelengths is reported. This represents the first experimental demonstration of an isotropic metasurface that provides wavefront control for arbitrarily polarized light.
Transparent Conducting Oxides (TCOs) enable the realization of practical plasmonic and metamaterial devices at the telecommunication frequency due to their low optical loss and CMOS compatibility. By employing a conventional dry-etching process, we have fabricated GZO plasmonic waveplates, which convert linearly polarized light into circularly polarized light.
Spontaneous emission patterns of electric and magnetic dipoles on different material surfaces were studied numerically and experimentally. The results show the modified behavior of electric and magnetic dipoles on metallic and HMM surfaces.
