AT＆T贝尔实验室的研究人员正在检查生成室中量子阱激光芯片的生成情况,这种芯片比米粒小,但价值却远远超过同样大小的钻石。这些激光器的成份包括镓、铟、砷化物和磷化物,在铟-磷化物基片上生成,在一张薄膜上可以安装成千个这种昂贵的芯片。 AT＆T贝尔实验室的研究人员在不断地改进这种激光器的制造工艺,以便降低成本,使它有可能为家庭和商业提供新的通信服务。他们研究工作的重点是量子阱激光器,贝尔实验室早在1976年就申请了技术专利, Researchers at AT & T’s Bell Labs are examining the production of quantum-well laser chips in a generation room that is smaller than the grain, but far more valuable than diamonds of the same size. The components of these lasers, including gallium, indium, arsenide and phosphide, are formed on an indium-phosphide substrate and thousands of such expensive chips can be mounted on a single film. Researchers at AT & T Bell Labs are constantly improving the laser manufacturing process to reduce costs and make it possible to provide new communications services for homes and businesses. The focus of their research work is quantum well lasers, Bell Labs as early as 1976 to apply for a patent,
