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…

Generation of entangled waveguided photon pairs by free electrons
Theis P. Rasmussen, Álvaro Rodríguez Echarri, Joel D. Cox +1
Entangled photon pairs are a key resource in future quantum-optical communication and information technologies. While high-power laser light propagating in bulk nonlinear optical c…
