By Jeff Hecht in Boston A PURE silicon laser has been demonstrated for the first time, offering the prospect of “photonic” silicon chips that communicate using light, and operate faster than electrical chips. No previous laser has inexpensively produced the elusive frequency band generated by the silicon laser, and the technology could soon be used in defence and communications. Researchers have long tried to get silicon to emit light, and have had some success by doping the material with other light-emitting elements. But until now they have not been able to produce laser light,
