Optical communication technology is needed to respond to the requirments both from trunk transmission systems and from acces network. Ultrafast signal transmission puts increasing burden on the driving electronics technology. Optical switching and multiplexing, when combined with functional electronic circuits may offer a reasonable solution to this bottleneck. We have conducted the study of basic research topics directly related to this problem : (1) development of ultrashort pulse source, (2) design of functional optoelectronic integrated circuit (OEIC), composed of CMOS and lateral pin PD.As for the pulse generation we compbined gain-switched semiconductor laser with multi-stage fiber-optic pulse compressor. Utilizing soliton effect in optical fiber we achieved the compression ratio of 500, resulting in 65 fs, the record pulse width starting from semiconductor laser source. As for OEIC,newly designed lateral pin photodiode can be fabricated by the standard manufacturing procedure of CMOS cirsuits. The fabrication was conducted by a collaborating company. The function of the OEIC is the compensation of clock skew. Fabricated chips are examined and the basic characteristics are confirmed.

无论是干线传输系统还是接入网，都需要光通信技术来满足需求。超快的信号传输给驱动电子技术带来了越来越大的负担。光开关和多路复用，当与功能电子电路相结合时，可以提供一个合理的解决方案，这个瓶颈。我们开展了与此直接相关的基础研究课题：（1）超短脉冲源的研制;（2）功能光电集成电路（OEIC）的设计。OEIC由CMOS和横向引脚PD组成，脉冲产生采用增益开关半导体激光器和多级光纤脉冲压缩器相结合。利用光纤中的孤子效应，我们实现了500的压缩比，从而使半导体激光源的记录脉冲宽度达到65 fs。对于光电集成电路，新设计的横向pin光电二极管可以通过CMOS电路的标准制造工艺来制造。制作是由一家合作公司进行的。OEIC的功能是补偿时钟偏差。加工芯片进行检查，并确认的基本特性。
