In the fields of optical communication and optical information processing, development of high-speed and high efficiency optical modulator is one of the most important targets. High speed optical modulator with LiNbO_3 is most promising as the ultra-high speed optical modulator in the next generation in place of the direct modulator using semiconductor lasers. The performance of this modulator was limited by the olsses in the signal electrode. The purpose of this research is to introduce superconducting electrodes with low loss and low dispersion characteristics to overcome this problem.In this year the following research has been made :1) performance evaluation using computor simulation2) change from He-Ne laser to semiconductor laser3) introduction of high quality Nb film as an electrode material4) introduction of automatic measurement of experimental data using GP-IB5) enlargement of substrate length from 15mm to 30mm

在光通信和光信息处理领域，发展高速、高效的光调制器是最重要的目标之一。 LiNbO_3高速光调制器最有希望成为下一代超高速光调制器，取代使用半导体激光器的直接调制器。该调制器的性能受到信号电极损耗的限制。本研究的目的是引入具有低损耗和低色散特性的超导电极来克服这个问题。今年进行了以下研究：1）使用计算机模拟进行性能评估2）从He-Ne激光器到半导体激光器的变化3）引进高品质铌薄膜作为电极材料4) 引进使用GP-IB自动测量实验数据5) 基板长度从15mm扩大到30mm
