光电子学尚处于初期发展阶段,至多只有20年的历史,但其应用的发展非常迅速。光电子学在通信方面的应用尤为突出,可望进一步的发展将成为信息化社会的基础。因此,迫切需要将大量的、多种信息迅速而准确地收集、处理与交换。本期JEE开始介绍光电子学技术现状及其应用。 Optoelectronics is still in the early stages of development, up to only 20 years of history, but its application is developing very rapidly. The application of optoelectronics in communications is particularly prominent, and it is expected that further development will become the foundation of the information society. Therefore, it is urgent to collect, process and exchange a large amount of various kinds of information promptly and accurately. This issue of JEE introduces the status of optoelectronics technology and its application.
