The Beginning of Truly Integrated Lasers?
Room-temperature infrared-emitting lasers grown on silicon could be the first step toward integrating optics for communications, computing and micro-optical devices.
A close-up of the chips that use germanium lasers to transmit data.
Room-temperature infrared-emitting lasers grown on silicon could be the first step toward integrating optics for communications, computing and micro-optical devices. Researchers at the Massachusetts Institute of Technology (Cambridge, U.S.A.) recently reported room-temperature lasing from a band-engineered germanium laser grown on silicon (Opt. Lett. 35, 679).
