On-Chip Laser that Could Have Your Computer Working at the Speed of Light

British physicists have made a breakthrough that brings the holy grail of ‘silicon photonics’ much closer. Cathal O’Connell reports. If you’re lucky enough to have a broadband connection by fibre optic cable, you already know about the speed of photonics – using light, not electric current, to send information. But while optical fibres use light to give us superfast internet, … Continue reading →
