A new generation of high-speed, silicon-based information technology has been brought a step closer by researchers in the UK. The team's research provides the first demonstration of an electrically driven, quantum dot laser grown directly on a silicon substrate (Si) with a wavelength (1300-nm) suitable for use in telecommunications.
