New optical device creates VUV light used in semiconductor manufacturing, photochemistry and materials science.

Optical vortex crystals will have impact on fields as diverse as microscopy, optical communications and photonics simulations.

A nanoscale device permitting asymmetric transmission of linearly polarized light could lead to significantly more efficient optical devices.

Metasurface diffusers in a layer that is 0.2 micrometers in thickness scatter light of a specific color and let other wavelengths pass undisturbed.

Three layers of phosphorous atoms are used to create a material for polarizing light that is tunable, precise, and extremely thin.

Experiments and theoretical ideas for how solids react to excitations with short laser pulses or the coupling of light and matter during irradiation with light.

The new material allows small and high-quality lasers that are expected to have applications for example in imaging, flow detection and wireless optical communication.

A special metasurface uses very deep, very narrow holes, rather than very tall pillars, to focus light to a single spot.
