UV & visible plasmonic metamaterials made of topological insulator
Plasmonic resonances are observed in metamaterials made of a topological insulator, Bi1.5Sb0.5Te1.8Se1.2, at the UV and visible frequencies due to the material’s interband transition and nontrivial surface conducting state.
Lorentz force metamaterial with giant optical magnetoelectric response
We demonstrate the first reconfigurable photonic metamaterial controlled by electrical currents and magnetic fields, providing first practically useful solutions for sub-megahertz and high contrast modulation of metamaterial ...
A magneto-electro-optical effect in a plasmonic nanowire material
Electro- and magneto-optical phenomena play key roles in photonic technology enabling light modulators, optical data storage, sensors and numerous spectroscopic techniques. Optical effects, linear and quadratic in external ...
