Cadmium sulfide nanowires can be used to create an all-optical photonic switch, a team at the University of Pennsylvania said. They combined the switch with others to create a logic gate for on-chip information processing. “Putting switches together lets you make logic gates, and assembling logic gates allows you to do computation,” said graduate student Brian Piccione. “We used these optical switches to construct a NAND gate, which is a fundamental building block of modern computer processing.” In creating the first such switch to be made of cadmium...Read full article
