A study first to demonstrate nanoscale all-optical logic circuits

Nice!

"an interdisciplinary team of researchers at Aalto University show how a new type of nanowire-based nanostructure enables light to perform logic functions, allowing simple addition and subtraction operations."

"'We're able to perform binary number calculations and show, for instance, how this nanostructure can carry out these functions just like a simple pocket calculator -- except that instead of using electricity, the nanostructure uses only light in its operation,' says Dr. Henri Jussila, who completed a post-doc at the university."
