Abstract :
Nanoscale light (ultimately laser) and surface plasmon (ultimately ´spaser´) sources for numerous potential nanophotonic applications have generated and continue to generate considerable research interest, with a variety of opticallyand electrically-pumped sources recently demonstrated. We show experimentally that beams of free electrons can be used to induce light emission from nanoscale planar photonic metamaterials, at wavelengths determined by both the metamaterial design parameters and the electron energy.
