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.
