Drift-induced nonreciprocity in image-polariton-mediated dipole emission
Christian Nicolaisen Hansen, Eduardo J. C. Dias, Christos Tserkezis +1
Electrical current bias offers a magnet-free route to nonreciprocal light propagation at the nanoscale. Here, we theoretically explore drift-induced nonreciprocity in graphene hete…

Active steering of cathodoluminescence through a generalized Smith-Purcell effect
Eduardo J. C. Dias, Álvaro Rodríguez Echarri, Theis P. Rasmussen +2
Optical metasurfaces can shape the near fields of energetic electrons, enabling Smith-Purcell (SP) emission. We introduce a generalized SP effect relying on finite periodic arrays…
