Researchers design holographic lenses based on plasma

Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...

With a little help, new optical material assembles itself

A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has demonstrated tiny concentric nanocircles that self-assemble into an optical material with precision and efficiency.

Integrated photonics meets electron microscopy

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics—circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes ...
