TOKYO - Scientists from Fujitsu Ltd. and The University of Tokyo have developed a laser that is capable of maintaining a stable output over a wide temperature range at speeds and frequencies useful for optical communications, the research team said Friday. The device could enable the creation of optical networking equipment that is smaller, cheaper and consumes less power than current devices, the leader of the research team said.
