项目摘要

Electro-magnetic sensors are of special concern because so many electrical equipments induce electro-magnetic radiation and the radiation affects the health of human being. To date electro-magnetic sensors are fabricated using crystal materials such as KIP. Electro-optic (EO) polymers are promising materiall for electro-magnetic sensing applications because of their large EO coefficients and processability to make a sensing device. In this research we had focused on the fabrication of new EO polymers with high EO efficiencies as well as high thermal stability. Because electro-magnetic sensors should preferably be serially-grafted waveguide structure with transparent polymer waveguide, we have fabricated the waveguide using UV-curable epoxy resin as a passive polymer waveguide.Among a variety of nonlinear optical polymers we investigated the use of a dye containing an acceptor composed with tricyano furan group that was coupled with azobenzene structure was very effective to enhance optical nonlinearity. To obtain thermally stable EO polymers, we had used poly arylether as a matrix of the dye. We had also used polyimide base EO-polymers as a thermally stable optical waveguides.Synthesized EO-polymer with tricyano-containing furan acceptor had excellent optical nonlinearity, about 3 times larger than that of standard Disperse-Red 1 attached polymer. A serially-grafted waveguide of the EO-polymer and passive polymer was fabricated to apply them to electro-magnetic sensor in a near-IR wavelength region.In conclusion, new type of EO-polymers were successfully synthesized and about 3 times larger optical nonlinearity than that of standard EO-polymer was attained. The serially-grafted waveguide of the EO-polymer with antenna structure is expected to be applied for evaluating electro-magnetic field in telecommunication wavelength region.

电磁传感器特别令人担忧，因为如此多的电气设备诱导电磁辐射和辐射会影响人类的健康。迄今为止，电磁传感器是使用晶体材料（例如KIP）制造的。电磁（EO）聚合物是电磁传感应用的有前途的材料，因为它们具有较大的EO系数和制造感应装置的加工性。在这项研究中，我们专注于制造具有高EO效率和高热稳定性的新EO聚合物。 Because electro-magnetic sensors should preferably be serially-grafted waveguide structure with transparent polymer waveguide, we have fabricated the waveguide using UV-curable epoxy resin as a passive polymer waveguide.Among a variety of nonlinear optical polymers we investigated the use of a dye containing an acceptor composed with tricyano furan group that was coupled with azobenzene structure was very effective to增强光学非线性。为了获得热稳定的EO聚合物，我们使用了聚芳基作为染料的基质。我们还使用了聚酰亚胺基碱EO聚合物作为热稳定的光学波导。与含三氯亚的Furan受体的合成EO聚合物具有出色的光学非线性，大约是标准分散红外1附着的聚合物的3倍。 EO聚合物的串行移植波导和被动聚合物被制造，以将它们应用于近IR波长区域中的电磁传感器。结论，在获得了新型的EO聚合物的新型EO聚合物，并且已成功合成了3倍的光学非线性，比标准的EO-Polymer的光学非线性大约是大约3倍。 EO聚合物具有天线结构的EO聚合物的串行移植波导有望用于评估电信波长区域中的电磁场。
