Physicists present a nanometer-sized light antenna with electrically modulated surface properties -- a breakthrough that could pave the way for faster computer chips. Physicists from Würzburg present ...

Since graphene has a low absorption coefficient in the absorption band, researchers generally use graphene as a carrier collection layer, and look for another strong light-absorbing material as the ...

Artist's impression of an electrically contacted optical antenna (left) and the quantum mechanical distribution of its surface electrons. The normal distribution is shown in yellow, while the change ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

It’s good fun to keep an eye on all sorts of things in your environment and on the basis of events in this environment to switch, for example, lamps or buzzers. To help with this, the light barrier ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual microphone captures tiny vibrations on the surfaces of objects caused by ...
