Bow tie-funnel combo best for conducting light, according to new research
Running computers on virtually invisible beams of light rather than microelectronics could make them faster, lighter and more energy-efficient. A version of that technology already exists in fiberoptic cables, but they're much too large to be practical inside a computer. A Vanderbilt University team found a solution in a formula familiar to college physics students -- a structure that's part bow tie, part funnel that concentrates light powerfully and nearly indefinitely, as measured by a scanning near-field optical microscope.
