Well scientists in the Bhavnagar University of Gujarat have done something very interesting… well it sounds interesting to a non-scientists anyways 🙂 They have trapped light in a “soup” of nano and micro particles!
Physicists at the Bhavnagar University in Gujarat, India, have demonstrated how to trap and retrieve light using a soup of micro- and nano-sized magnetic spheres.1 The unusual fluid, they say, works at room temperature, holds photons for far longer than other systems, and can also be tuned with a magnet to store any wavelength of visible light. ‘The discovery could pave the way for lab-on-a-chip devices for processing optical information,’ Rasbindu Mehta, who led the team, told Chemistry World.
Why is it important? Because it can revolutionize the world of computing far beyond our imagination!
For over a decade scientists have been working towards light-based computing: where circuits control photons – particles of light – in the same way that they currently manipulate electrons. Photon-based computing should be faster than electronics. It would also cut out the ungainly components used to convert between the optical signals that transmit data and the electrical signals that manipulate and store it.
