Coherent nanophotonic electron accelerator
Particle accelerators are essential tools in a variety of areas of industry, science and medicine1–4. Typically, the footprint of these machines starts at a few square metres for medical applications and reaches the size of large research centres. Acceleration of electrons with the help of laser light inside of a photonic nanostructure represents a microscopic alternative with potentially orders-of-magnitude decrease in cost and size5–16. Despite large efforts in research on dielectric laser acceleration17,18, including complex electron phase space control with optical forces19R...
