If computers calculated using light instead of electrons, they’d be more energy efficient and at least a thousand times faster than they are today. Unfortunately, the optical analogs of computer circuits are too bulky to vie with electronic ones. Now researchers have built a simple, micrometer-sized circuit that integrates five lasers (Nano Lett., DOI: 10.1021/nl302809a). Such a circuit could serve . . .
