Transverse hypercrystals formed by periodically modulated phonon-polaritons
Hanan Herzig Sheinfux, Minwoo Jung, Lorenzo Orsini +10
Photonic crystals and metamaterials are two overarching paradigms for manipulating light. Combining the two approaches leads to hypercrystals: hyperbolic dispersion metamaterials t…
Tunable plasmons in ultrathin metal films
Rinu Abraham Maniyara, Daniel Rodrigo, Renwen Yu +7
The physics of electrons, photons, and their plasmonic interactions changes greatly when one or more dimensions are reduced down to the nanometer scale. For example, graphene shows…
Near-field photocurrent nanoscopy on bare and encapsulated graphene
Achim Woessner, Pablo Alonso-González, Mark B. Lundeberg +14
Opto-electronic devices utilizing graphene have already demonstrated unique capabilities, which are much more difficult to realize with conventional technologies. However, the requ…
Resonant Visible Light Modulation with Graphene
Renwen Yu, Valerio Pruneri, F. Javier Garcia de Abajo
Fast modulation and switching of light at visible and near-infrared (vis-NIR) frequencies is of utmost importance for optical signal processing and sensing technologies. No fundame…
