Shaping the future of light through reconfigurable metasurfaces

The technological advancement of optical lenses has long been a significant marker of human scientific achievement. Eyeglasses, telescopes, cameras, and microscopes have all literally and figuratively allowed us to see the ...

A vertical matrix X-ray detector for multi-energy discrimination

There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...

On-chip photodetection: Two-dimensional material heterojunctions

Photonic integrated circuits (PICs) use photons as information carriers and are expected to solve the bottleneck problems of microelectronic chips in terms of speed, power consumption and integration density with their advantages ...

Optical cavities could provide new technological possibilities

A research team from NTNU is studying a topic called optical cavities and how the light trapped in them interacts with atoms, molecules and other particles. The technology could prove valuable for the development of energy-efficient ...

Ultrafast dynamics of topological material probed under pressure

A team led by Prof. Su Fuhai from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS), together with researchers from the Aerospace Information Research Institute, and the Center for ...

Laser bursts drive fastest-ever logic gates

A long-standing quest for science and technology has been to develop electronics and information processing that operate near the fastest timescales allowed by the laws of nature.

A zero-cost way to improve neutron scattering resolution by 500%

Scientists pushing the limits of the world's most advanced neutron scattering instruments know that a small amount of distortion in their measurements is inevitable. For some experiments, this distortion is easily accounted ...

A new window into the world of attosecond phenomena

They are everywhere, around us and within us. Phenomena lasting trillionths of a second form the core of chemistry and biology. It is only recently that we have begun to try to accurately record their actual course, with ...
