A landmark of nanophotonics is the design of nanostructured materials (metasurfaces, photonic crystals, nanoresonators, etc.) to tailor the interaction of light with matter, either by shaping light propagation at the nanoscale, or by controlling emission from atoms and molecules. In this talk, I will show how one can enhance and tailor radiation from high-energy particles, such as free electrons and x-rays with engineered nanophotonics structures. I will present a framework to model, tailor, enhance, and even optimize radiation from free electrons and other high-energy particles interacting with nanophotonic structures. I will then describe the building of a featured experimental setup to record spectrally-resolved light emission from free electrons interacting with nanophotonic structures. I will focus on the example of nanophotonic flatbands in photonic crystals, which can be used to enhance free-electron radiation and acceleration by orders of magnitude by overcoming phase-matching limitations. I will utilize our methods to demonstrate nanophotonic enhancement of coherent cathodoluminescence from free electrons and discuss new frontiers in the quantum optics of free electrons PB - JACoW Publishing CP - Geneva, Switzerland ER -
