Visions 12: Photonics

Novel microstructures that steer light in the same way as semiconductor devices manipulate electrons may soon transform telecommunications

Visions 12: Photonics

Futuristic fictional scenarios often depict information stored not on disks and tapes but in some kind of transparent ‘crystal.’ 

The inference is that photons of light rather than electrons are the signal carriers. 

Indeed creating ultrafast alloptical computers and communications have been a physicist’s dream for many years. 

Light has several advantages over electrons as an information carrier: it’s very much faster and has the potential to convey vast amounts of data with lower power losses.
