| Research Abstract |
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.
