Transistors in computer chips work electrically but data can be transmitted more quickly using light. For this reason, researchers have long been looking for a way to integrate lasers directly in silicon (Si) chips. Scientists now have developed a compatible semiconductor laser made of germanium and tin whose efficiency is comparable with conventional GaAs semiconductor lasers on Si.
