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.  

A new method for generating quantum-entangled photon pairs employs nonlinear metasurfaces to enhance and tailor photon emissions – an important step towards creating...
