项目摘要

Future ultra-high-speed optical transmission network systems require flexibility of time division and wavelength division multiplexing. Optical solitons are most suitable for such systems. Research on optical soliton based ultra-high speed communication systems have been performed both in theory and in experiments. Particular emphases are placed on soliton control and dispersion management in order to achieve wavelength multiplexing both of which are our original contributions. In experiments, we have demonstrated a stable ten Gigabit/second optical soliton transmission over tramspacific distance using guiding filter and frequency sliding in recirculating fiber loop. In addition preliminary experiments of two ten Gigabit/second wavelength division multiplexing were performed.In theory, we have shown for the first time that for the successful transmission of wavelength division multiplexed solitons in fibers with repeated amplifications, a dispersion decreasing fiber is most effective. This idea was demonstrated in a experiment at Bell Laboratories of 8 times 10 Gigabit/second transmission over 9,000 Kilometers. Similar experiments are being planned also by our group.In addition to these results, we have studied various methods of soliton control and of coding information on soliton parameters. The results were published shown in the list of publications.

未来的超高速光传输网络系统需要时分复用和波分复用的灵活性。光学孤子最适合此类系统。基于光孤子的超高速通信系统的研究已经在理论和实验上进行。特别强调孤子控制和色散管理，以实现波长复用，这两者都是我们的原创贡献。在实验中，我们利用循环光纤环路中的引导滤波器和频率滑动，展示了跨太平洋距离上稳定的十吉比特/秒光孤子传输。此外还进行了两个十吉比特/秒波分复用的初步实验。从理论上讲，我们首次证明，为了在重复放大的光纤中成功传输波分复用孤子，色散降低光纤是最有效的。贝尔实验室的一项实验证明了这一想法，该实验在 9,000 公里范围内实现 8 倍 10 Gigabit/秒的传输。我们小组也正在计划类似的实验。除了这些结果之外，我们还研究了孤子控制和孤子参数信息编码的各种方法。结果已发表在出版物清单中。
