一、概述自1960年汤斯和梅曼等研制成第一台红宝石激光器以来,激光器的发展迅速异常.六十年代中期制成的半导体异质结(AlGa)As/GaAs 激光器,使光学通信具备了高性能的半导体激光源,它们发射的激光的波长正好处于损耗甚低的光导纤维的低耗区.从1977年5月开始,由美国贝尔电话实验室设计的光纤通信系统已用于芝加哥市的商业电话网.就国际上说,八十年代将是光纤通信系统从原型阶段迅速步入生产阶段的成年时代,而对电话系统、计算机互联、仪表 I. Overview Since the first ruby ​​lasers were developed by Towns and Mehmet in 1960, the development of lasers has been rapidly developed. The AlGaAs As / GaAs lasers made in the mid-1960s have made optical communications High-performance semiconductor laser sources emit laser light at precisely the low loss area of ​​low loss optical fibers. Since May 1977, a fiber optic communications system designed by the Bell Telephone Laboratory in the United States has been used in Chicago Internationally, the 1980s will be an era of fiber-optic communication systems that are rapidly entering the production phase from the prototyping stage, while the telephone systems, computer networks, instrumentation
