"artificial neurons activated by event-based photonics... waveguide-coupled phase-change... become stronger or weaker (synaptic plasticity)... synapses not hardware elements but coded as a result using optical pulses... integrate several thousand neurons on single chip and connect optically... higher bandwidth, less energy... nonvolatile, phase-change material switched between amorphous and crystalline structures with highly ordered atomic lattice enabling permanent data storage even without energy supply...
