项目摘要

New and simple optical functional devices using a chiral or diamagnetic polymer with nonlinearity has been studied under this Grant-in-Aid for Scientific Research (C). Operation principle in these devices is based on the TE-TM mode conversion through the off-diagonal element in dielectric tensor of the chiral polymers such as nonlinear dye-doped polymenthylmethacrylate (PMtMA) and coploymer of MtMA/BzMA.Through the theoretical and experimental analyses, the following results were obtained.(1) Polymer waveguide-type optical isoplator with an isolation ratio of about 15dB was demonstrated for the first time, using the Poly(MtMA/BzMA) slab waveguide.(2) Basic operation of the polymer waveguide-type optical modulators, which are consisting of the nonlinear NPP or FMA dye-doped PMtMA slab waveguides, were comfirmed thoretically and experimentally. The obtained moduration indeces were 25〜50%.(3) To improve the modulation efficiency, several methods to fabricate the channel-type PMtMA waveguide were attempted.These results were reported on the two journals and three proceedings of POF and PAT international conferences. So, the investigator would like to express his sincere thanks for this Grant-in-Aid for Science Research.

在科学研究补助金（C）下，研究了使用具有非线性的手性或抗磁性聚合物的新型简单光学功能器件。这些器件的工作原理是基于手性聚合物如非线性染料掺杂的聚甲基丙烯酸甲酯（PMtMA）和MtMA/BzMA共聚物介电张量中的非对角元引起的TE-TM模式转换。(1)利用Poly（MtMA/BzMA）平板波导，首次实现了隔离度约为15 dB的聚合物波导型光等离子体。(2)从理论和实验上证实了由非线性NPP或FMA染料掺杂PMtMA平板波导构成的聚合物波导型光调制器的基本工作原理。所得改性指数为25 ~ 50%。(3)为了提高调制效率，我们尝试了几种制作通道型PMtMA波导的方法，这些结果在两种期刊和三次POF和PAT国际会议上发表。因此，研究者对此次科研资助计划表示衷心的感谢。
