韩国光导元器件技术的现状１．引论自１９７０年康宁玻璃公司实现２０ｄＢ／ｋｍ光纤损耗以来，光纤技术和相关的光子学取得重大进展［１］。低损耗光纤的出现在实施高数据率通讯系统方面是有益的。它为与普通传输系统概念完全不同的宽带通讯应用新时代的到来开辟了道路。... Status of Korean Optoelectronic Components Technology 1. Introduction Since Corning Glass achieved fiber loss of 20 dB / km in 1970, significant progress has been made in optical fiber technology and related photonics [1]. The emergence of low loss optical fibers is beneficial in implementing high data rate communication systems. It opens the way for a new era of broadband communications applications that is fundamentally different from the concept of ordinary transmission systems. ...
