Beamstop-free small-angle X-ray scattering for multiscale structure measurement of high-energy-density plasma

The advent of free-electron lasers has enabled in-situ small-angle X-ray scattering (SAXS) measurements of laser-produced high-energy-density plasma at solid density, with nanometer- and femtosecond-scale resolution. Such plasmas generally exhibit gentle density gradients, which...

Scalable design of single-photon emitters integrated on silicon with a crossed-waveguide architecture

The scalable integration of deterministic telecom-band single-photon sources into silicon photonic circuits is a critical challenge for quantum information processing, primarily bottlenecked by the stringent alignment tolerances of conventional hybrid coupling schemes. To overcom...
