Nano-structured glass creates new type of computer memory

Humans have been using and making glass for thousands of years, and it’s pretty much always served the same purpose— to make shit that you can see through. But researchers at the University of Southampton in the UK have made nano glass, a substance in which the way light travels through the glass can be controlled to store data.

Researchers at the University of Southampton used nano-structures to create millimeter-sized “monolithic glass space-variant polarization converters,” which ultimately changes the way light travels through and is stored in glass. These “whirlpools” of light data can be read like information stored in optical fibers — allowing for “more precise laser material processing, optical manipulation of atom-sized objects, ultra-high resolution imaging and potentially, table-top particle accelerators.”
