Optical lens can transfer digital information without loss

(Phys.org)—Researchers have designed an optical lens that exhibits two properties that so far have not been demonstrated together: self-focusing and an optical effect called the Talbot effect that creates repeating patterns ...

Physicists design ultrafocused pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Physicists master unexplored electron property

While the charge and spin properties of electrons are widely utilized in modern day technologies such as transistors and memories, another aspect of the subatomic particle has long remained uncharted. This is the "valley" ...

Scientists announce the quest for high-index materials

An antenna is a device capable of effectively transmitting, picking up, and redirecting electromagnetic radiation. Typically, antennas are macroscopic devices operating in the radio and microwave range. However, there are ...

Vortex photons from electrons in circular motion

Researchers at IMS and their coworkers have shown theoretically and experimentally that a high energy electron in circular/spiral motion radiates vortex photons from the radio wavelength to gamma rays. This greatly broadens ...

The wave nature of light in super-slow motion

Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Friedrich Schiller University Jena (FSU) have accomplished a quantum leap in light research. They have managed to capture the behaviour of extremely ...
