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 ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

Light microscopy is the only way in which we can look inside a living cell, or living tissues, in three dimensions. An electron microscope only gives a two-dimensional view, and the organic sample ...

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 ...

Surface plasmons are collective oscillations of free electrons that occur at the interface between a metal and a dielectric medium, such as air or glass. These oscillations are coupled with ...
