已经发表了许多关于导波光学系统应用于通讯的文章,但需看到光学通讯仅仅还是一种处于发展初期的新技术。现代光学是以激光这一光源的发展为起点的。自从1837年莫斯(morse)发明电报以来,已经发展了一个无线电、电视、计算机的电子世界。现在,现代光学给我们带来了光学通讯。但不能忘记激光,特别是半导体激光是唯一的既可用于通讯,也可用于大量信息处理的能源。光学静电印刷有两种激光驱动的印刷系统已经达到商业实用阶段:光学印刷板的制作系统、光学-静电计算机印刷系统。另外,激光驱动的文件扫描系统和传真收发机也正在试验和生
Many articles have been published on the application of guided-wave optical systems to communications, but it is important to note that optical communications is still just a new technology at an early stage of development. Modern optics is based on the development of a laser as a light source. Since mss invented the telegraph in 1837, it has developed an electronic world of radio, television, and computer. Nowadays, modern optics bring us optical communications. But you can not forget that lasers, and especially semiconductor lasers, are the only energy sources that can be used both for communications as well as for massive information processing. Optical Electrostatic Printing Two laser-driven printing systems have reached the commercial practical stage: a production system for optical printing plates, an optical-electrostatic computer printing system. In addition, laser-driven document scanning systems and fax transceivers are also being tested
