  - Extracting light from silicon is a longstanding challenge in modern engineering
    and physics. While silicon has underpinned the past 70 years of electronics advancement,
    a facile tunable and efficient silicon-based light source remains elusive. Here,
    we experimentally demonstrate the generation of tunable radiation from a one-dimensional,
    all-silicon nanograting. Light is generated by the spontaneous emission from the
    interaction of these nanogratings with low-energy free electrons (2–20 keV) and
    is recorded in the wavelength range of 800–1600 nm, which includes the silicon
    transparency window. Tunable free-electron-based light generation from nanoscale
    silicon gratings with efficiencies approaching those from metallic gratings is
    demonstrated. We theoretically investigate the feasibility of a scalable, compact,
    all-silicon tunable light source comprised of a silicon Field Emitter Array integrated
    with a silicon nanograting that emits at telecommunication wavelengths. Our results
    reveal the prospects of a CMOS-compatible electrically-pumped silicon light source
    for possible applications in the mid-infrared and telecommunication wavelengths.@eng
