Phase-resolved mapping of plasmonic resonances at nanostructures — •Tim Dauwe1,2, Hugo Lourenco-Martins1,2, Murat Sivis1,2, Jakob Hagen1,2, and Claus Ropers1,21Max Planck Institute for Multidisciplinary Sciences, 37077 Göttingen, Germany — 2IV. Physical Institute, University of Göttingen, 37077 Göttingen, Germany

In this contribution, we study resonant plasmonic nanostructures by a combination of inelastic electron-light scattering techniques. We investigate metallic nanorods using electron-energy loss spectroscopy (EELS) and photon-induced near-field electron microscopy (PINEM), elucidating spectrally-dependent mode profiles and symmetries using spontaneous and stimulated interactions. We explore multicolor excitation and nonlinear wave mixing as contrast mechanisms accessing spatial phase profiles and local nonlinear response.
