Researchers Demo All-Optical Nanowire Switching

Researchers at the University of Pennsylvania have demonstrated the feasibility of using all-optical switches for possible use in computing. Their research, published in Nature Nanotechnology, demoed all-optical switching in individual cadmium sulfide nanowires. They also demoed a functional NAND gate built from multiple switches.
