The objective of this project research is a development of a system for a Ultrafast photonic time-Space conversiOn and transmission. Increasing demands for multi-media information in a networked society requires an optical fiber communication system with ultra-high transmission capaqity and ultrafast processing system. Since data in the advanced networks are ultrafast ones, it is necessary to develop an ultra fast optical information processing system whose processing speed is over Tbps, at least. One promissing approach is a paralle processing to realize such an ultrafast information proces slng.For this purpose, we have proposed the novel optical ultrafast two-dimensional space -to- time -to- two-dimensional space conversion techuique among image signals and time sequential ones with an ultra-fast pulse laser. By using the proposed technique, we constructed a femtosecond pulse optical information processing system and demonstrated fundamental functions of the optical routing system for an ultrafast packet switching. As a result of experimental verification, we confirmed that the proposed technique is compatible with the current ultrafast optical fiber cornmunication system. To demonstrate the capability of the constructed system, we implemented the ultrafast header recognition whose processing rate is over 600Gbps. From the results of this research, we can 6btain the important knowledge, with which the proposed technique would become an ultra fast optical infonnation processing sYstem in the next generation of networked society.

本项目研究的目标是开发一种超快光子时空转换和传输系统。网络社会对多媒体信息的需求日益增长，需要具有超高传输能力和超高速处理能力的光纤通信系统。由于先进网络中的数据是超高速的，因此有必要开发一种处理速度至少在Tbps以上的超高速光信息处理系统。为了实现这种超快的信息处理，一种有希望的方法是并行处理。为此，我们提出了一种新颖的光学超快二维空间-时间-时间-二维空间转换技术，该技术利用超快脉冲激光在图像信号和时间序列之间进行转换。利用所提出的技术，我们构建了一个飞秒脉冲光信息处理系统，并演示了超快分组交换光路由系统的基本功能。经实验验证，该技术与现有的超高速光纤通信系统兼容。为了验证所构建系统的性能，我们实现了处理速率超过600Gbps的超高速报头识别。从研究结果中，我们可以获得重要的知识，利用这些知识，所提出的技术将成为下一代网络社会中的超高速光信息处理系统。
