理论物理研究与光纤通信新概念探索

THEORETICAL PHYSICS AND THE EXPLORATION OF NEW CONCEPTS IN FIBEROPTIC COMMUNICATION

文章从光纤通信的基本概念出发，介绍了新一代光纤通信系统———光孤子通信系统研究中与物理学有密切关系的一些方面，并结合作者近年来的探索性工作，较深入地讨论了这一首例非线性通信系统的关键问题，提出了孤子信道的ＲＬＬ（ｒｕｎｌｅｎｇｔｈｌｉｍｉｔｅｄ）编码和孤子－混沌通信的概念，并重点介绍了光孤子－呼吸子通信的基本思想和主要结果．

Beginning with the basic concepts of optical communications,several aspects closely related to the physics of optical soliton communications are introduced.The key problems of this nonlinear communication system are discussed in depth.We propose some new concepts such as RLL channel coding of solitons and soliton-chaos communication,and introduce the basic ideas and main results of optical soliton-breather communication.
