Researchers Develop First Nonvolatile All-Optical Chip Memory Based on Phase-Change Materials

In a potentially significant leap toward optical computers, researchers at the Karlsruhe Institute of Technology (KIT) in Germany and the universities of Münster, also in Germany, and Oxford and Exeter, both in the UK, have developed the first nonvolatile all-optical chip memory based on phase-change materials that change their optical properties depending on the arrangement of the atoms, allowing for the storage of several bits in a single cell.
