SCIENCE - Novel quantum dot laser paves the way for lower-cost photonics

With the explosive growth of bandwidth demand in telecommunications networks, experts are continually seeking new ways to transmit increasingly large amounts of data in the quickest and cheapest ways possible. Photonic devices—which convert light to electricity and vice versa—offer an energy-efficient alternative to traditional copper network links for information transmission. Unfortunately, these devices are also almost always prohibitively pri ...
