(OBJECTIVE) The aim of the present project is to perform basic experiments of time domain signal multiplexing based on high speed bistable semiconductor lasers, in order to find out the feasibility of this approach for a futuristic high speed digital information system.(METHOD OF INVESTIGATION) To achieve the above mentioned objective, the following procedures were performed: (a)device assembly; (b) measurement and evaluation of the transient characteristics of bistable lasers; (c) two-channel optically triggered timedivision-multiplexing experiment, and (d) investigation of the instability of bistable semiconductor lasers, especially the chaos characteristics.(MAJOR ACHIEVEMENTS) 1) Conditions for high speed switching of bistable semiconductor lasers are obtained.(2) A combination of bistable semiconductor lasers with planar photoconductive devices is demonstrated to be effective in achieving optically triggered TDM digital system, with good fan-out characteristics.(3) Two channel TDM experiment was performed successfully without cross talk.(4) Instability of bistable semiconductor laser includes self-sustained pulsation and chaos phenomena, deterministic random oscillation. Only under strong modulation condition, self-pulsating bistable semiconductor laser showed chaotic response, in qualitative accordance with computer simulation.

（目的）本项目的目的是进行基于高速双稳态半导体激光器的时域信号复用的基础实验，以探索该方法在未来高速数字信息系统中的可行性。（调查方法）为实现上述目标，执行以下程序：(a)装置组装；(b)双稳激光器瞬态特性的测量与评价；(c)双通道光触发时视复用实验；(d)双稳半导体激光器的不稳定性，特别是混沌特性的研究。(1)获得了双稳态半导体激光器高速开关的条件。(2)双稳型半导体激光器与平面光导器件的组合是实现光触发TDM数字系统的有效方法，具有良好的扇出特性。(3)成功进行了无串扰的双通道时分复用实验。(4)双稳半导体激光器的不稳定性包括自持续脉动和混沌现象、确定性随机振荡。只有在强调制条件下，自脉动双稳半导体激光器才表现出混沌响应，与计算机模拟结果定性一致。
