Researchers at Southampton University have developed new nanostructured glass, turning it into new type of computer memory. These new devices change the way light travels through glass, generating whirlpools of light that can then be read in much the same way as data in optical fibres. This enables more precise laser material processing, optical manipulation of atom-sized objects, ultra-high resolution imaging and potentially, table-top particle accelerators. Information can be written, wiped and rewritten into the molecular structure of the glass using a laser. According to the researchers, at sufficient intensities, ultra-short laser pulses can be used to imprint tiny dots like 3D pixels called voxels in glass.
