光电子技术作为电子技术的一部分 ,本身也有许多门类和应用 ,而近年发展最快的要算光纤通信、激光二级管阵列、红外探测器阵列及其系统 ,而光纤放大器又作为光电器件的新星一经发明便使光纤通信系统的距离无限延伸。一、光纤通信系统的研究水平遥遥领先于实用系统的要求关于光 As a part of electronic technology, optoelectronic technology itself has many categories and applications. In recent years, optical fiber communication, laser diode array, infrared detector array and its systems have been the fastest growing, while optical fiber amplifiers are once again newcomers to optoelectronic devices The invention will make the distance of optical fiber communication system extend indefinitely. First, the research level of optical fiber communication system far ahead of the practical requirements of the system on the light
