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. The team, led by professor Ritesh Agarwal, grew nanowires, grew a silicon oxide shell on their surfaces to improve their optical properties, cut a nanowire, pumped light through it, and turned off the light, making the device a switch.
