Synthesizing free-electron wave functions by stimulated near-field interactions
Álvaro Rodríguez Echarri, Albert Polman
Stimulated electron-optical-near-field interactions imprint a coherent, phase-coherent modulation on the wave function of a free electron, of which the free-space dispersion subseq…
Plasmon-Enhanced Second-Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures
Saad Abdullah, Philipp K. Jenke, Andrew P. Weber +8
The intrinsically weak nonlinear optical response of existing materials, further constrained by symmetry-forbidden second-order processes in centrosymmetric media, severely limits…
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…
Roadmap for Photonics with 2D Materials
F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
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…
Nonlinear photoluminescence in gold thin films
A. Rodríguez Echarri, F. Iyikanat, S. Boroviks +3
Promising applications in photonics are driven by the ability to fabricate crystal-quality metal thin films of controlled thickness down to a few nanometers. In particular, these m…
