Researchers demonstrate attosecond boost for electron microscopy

A team of physicists from the University of Konstanz and Ludwig-Maximilians-Universität München in Germany have achieved attosecond time resolution in a transmission electron microscope by combining it with a continuous-wave ...

Physicists make electrical nanolasers even smaller

Researchers from the Moscow Institute of Physics and Technology and King's College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported ...

3-D laser damage positioned by deep-learning method

Traditional online damage detection schemes can directly detect and characterize damage by imaging optical components. However, due to optical resolution, noise, shadows and reflections, the small-size damage points cannot ...

Space-time metasurface makes light reflect only in one direction

Light propagation is usually reciprocal, meaning that the trajectory of light travelling in one direction is identical to that of light travelling in the opposite direction. Breaking reciprocity can make light propagate only ...

Breakthroughs seen in artificial eye and muscle technology

Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens that is essentially a flat, electronically controlled artificial ...
