项目摘要

The objective of this project research is a development of a femtosecond pulse optical information processing system. Increasing demands for multimedia information in a networked society requires an optical fiber communication system with ultra-high transmission capacity and ultrafast switching system. To realize such an ultrafast information processing, it is necessary to develop an ultra fast optical information processing system whose processing speed is over Tbps, at least.For this purpose, we have proposed the novel optical ultrafast two-dimensional space-to-time-to-two-dimensional space conversion technique 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 the optical 2D-space-to-time-to-2D-space conversion system. As a result of experimental verification, we confirmed that the proposed : technique is compatible with the current ultrafast optical fiber communication system. To demonstrate the capability of the constructed system, we implemented the character image transmission and transform.From the results of this research, we can obtain the important knowledge, with which the proposed technique would become an ultra fast optical information processing system in the next generation of networked society.

该项目研究的目标是开发飞秒脉冲光学信息处理系统。网络社会对多媒体信息的需求日益增长，需要具有超高传输容量和超高速交换系统的光纤通信系统。要实现这样的超快信息处理，需要开发一种处理速度至少超过Tbps的超快光学信息处理系统。为此，我们提出了一种利用超快脉冲激光器实现图像信号和时间序列信号之间的新型光学超快二维空间到时间到二维空间转换技术。利用所提出的技术，我们构建了飞秒脉冲光学信息处理系统，并演示了光学二维空间到时间到二维空间转换系统。通过实验验证，我们确认所提出的技术与当前的超快光纤通信系统兼容。为了展示所构建系统的能力，我们实现了字符图像传输和转换。从这项研究的结果中，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快速光学信息处理系统。
