The research area of nanophotonics, the study of light at the nanoscale, has experienced a dramatic growth in recent years. To further advance this field, it is essential to develop novel characterization techniques that are able to generate, probe and control light at length scales far below the diffraction limit of light, at a broad energy range, and at femtosecond time scales. Recently, electron-beam spectroscopies have emerged as powerful probes in nanophotonics research, fueled by the advent of improved microscopes and the exploration of brand-new techniques. In particular, taking advantage of the extremely high spatial resolution in electron beam microscopy, novel techniques have appeared that combine the use of electron beams with optical spectroscopy. Cathodoluminescence imaging spectroscopy (CL) and Electron Energy Loss Spectroscopy (EELS) use high-energy beams in an SEM or TEM. Photoemission Electron Microscopy (PEEM) and Scanning Tunneling Microscopy (STM) enable electron beam spectroscopies to be performed at lower energies and are also becoming increasingly popular to provide insight into optical phenomena at the nanoscale. Electron beam Phase-shaping techniques are now unveiling new properties of optical materials. Photon-induced near-field electron microscopy (PINEM) and newly emerging techniques that combine photons and e-beam interactions are revealing ultrafast phenomena with an unprecedented combination of spectral, spatial, and temporal resolutions.
