“The future of faster, more efficient information processing may come down to light rather than electricity. Mark Lawrence, a postdoctoral scholar in materials science and engineering at Stanford, has moved a step closer to this future with a scheme to make a photon diode—a device that allows light to only flow in one direction—which, unlike other light-based diodes, is small enough for consumer electronics.
All he had to do was design smaller-than-microscopic structures and break a fundamental symmetry of physics…”
