In December 1995, a researcher at a medium-sized company in Japan announced the development of a long-sought device—a laser diode operating at room temperature that emits blue light. In his Perspective, Fasol describes the development of this device, which may have major applications in optical data storage and computer displays, and the corporate culture that fostered its creation.
