Paint-on laser could rescue computer chip industry

Abstract:
Researchers at the University of Toronto have created a laser that could help save the $200-billion dollar computer chip industry from a looming crisis dubbed the “interconnect bottleneck.” To tackle this problem, Sargent, a Canada Research Chair in Nanotechnology, created the new laser using colloidal quantum dots — nanometre-sized particles of semiconductor that are suspended in a solvent like the particles in paint. “We’ve made a laser that can be smeared onto another material,” says Sargent. “This is the first paint-on semiconductor laser to produce the invisible colours of light needed to carry information through fiber-optics. The infrared light could, in the future, be used to connect microprocessors on a silicon computer chip.”
