Lenovo loves its red mousing nipple, Apple digs its aluminum and IBM adores those light pulses. Nearly two full years after we heard this very company touting breakthroughs in science thanks to a nanophotonic switch, in flies a similar technique from Yorktown Heights that could "greatly further energy efficient computing." As the story goes, gurus at IBM have figured out how to replace electrical signals that communicate via copper wires between computer chips with tiny silicon circuits that chat using pulses of light. The device is called a nanophotonic avalanche photodetector, and according to Dr. T.C. Chen, this ki
