These lasers are the single most important step towards building computer chips that use light instead of electricity for ultra-fast and efficient on- and off-chip communications. Producing electrically powered nanoscale lasers has proven to be one of the toughest tasks facing electronic and photonic engineers. Over the last few years we have created very small on-chip lasers, but they need to be powered by a large, off-chip laser. We have also produced electrically powered (i.e. self-contained) lasers, but they require very cold temperatures (...
