A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not ...

A flash of light has turned a sheet of atoms into a dance floor. In a feat of precision physics, researchers from Cornell and ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

We present a technique called white-light diffraction tomography (WDT) for imaging microscopic transparent objects such as live unlabelled cells. The approach extends diffraction tomography to ...

A material that is capable of the “reverse diffraction” of light and that is inspired by butterfly wings has been made by researchers in the US. The structure combines features of the butterfly’s ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Researchers have developed a new algorithm for recovering the 3D refractive index distribution of biological samples that exhibit multiple types of light scattering. Researchers have developed a new ...
