It is based on

light

and speaks Italian, the technology that promises to

make wireless connections a

hundred times faster and more efficient

, with a

technological leap

comparable to that of cable connections with the arrival of optical fibers.

This new frontier of technology is opened by the

chip

born from the research led by the Politecnico di Milano and conducted in collaboration with the Scuola Superiore Sant'Anna of Pisa, the Californian University of Stanford and the British University of Glasgow, as part of the European project. Superpixel.

Described in the journal Light: Science & Applications, the chip allows for the

separation of light beams

even if they are superimposed on each other and if the shape in which they arrive at their destination has changed and is unknown.

The 5-millimeter

-sized

silicon



chip is

able to separately receive the light beams thanks to

a multitude of microscopic optical antennas

and manipulate them, ordering them, thanks to a network of

integrated

interferometers .

By eliminating in this way the interference between the light beams, the chip allows to

manage

a

quantity

of information

at least one hundred times greater than

that of current high-capacity wireless systems, of over 5000 GHz.

Possible

applications



are many, says Andrea Melloni, director of Polifab, the micro and nanotechnology center of the Politecnico di Milano, and include "high-precision positioning and localization systems for self-driving vehicles, sensors and remote object recognition, portable devices and wearables for augmented reality and new investigation techniques for biomedical applications ".



Thanks to the collaboration that led to this result, Italy is

Italy

in a

leadership

position on photonic technologies for communication, sensors and biomedical ", observes Marc Sorel, professor of Electronics at the TeCIP Institute (Telecommunications, Computer Engineering, and Photonics Institute) of the Sant'Anna School of Advanced Studies.
