Opto-mechanical non-reciprocity in fiber

The internet era that we live in depends completely on the transfer of vast amounts of information over optical fibers. Optical fibers are literally everywhere. In fact, the overall length of optical fibers installed on our ...

Gravitational lenses could allow a galaxy-wide internet

As Carl Sagan once said, "The sky calls to us. If we do not destroy ourselves, we will one day venture to the stars." And our first emissaries to the stars will be robotic probes. These interstellar probes will be largely ...

How flashlight fish communicate with light signals in schools

Flashlight fish have the ability to generate situation-specific blink patterns resembling a visual Morse code. Researchers at Ruhr-Universität Bochum have shown in laboratory and field experiments that the animals use these ...

Shaping radio signals using light

Shaping radio signals using photonics technologies seems like a detour. But the versatility of current programmable silicon photonic circuits can open new possibilities according to researchers of the University of Twente. ...

Sustainable optical fibers developed from methylcellulose

Researchers from Tampere University and Aalto University have developed optical fibers from methylcellulose, a commonly used cellulose derivative. The finding opens new avenues to short-distance optical fibers using sustainable ...
