将新型软光电功能材料——离子液体注入到内径为0.32mm的石英管中制成了能同时传输光电信号的传输媒介,选用10种不同的离子液体,实验研究了传输媒介的主要特性。研究结果发现,当传输电信号频率大于10Hz时,光电信号之间互不影响;其数值孔径可达0.554,优于传统的光纤传输媒介;其衰减特性与波长和离子液体种类有关;不同离子液体制成的传输媒介其阻抗相差可达一个量级以上,并对温度的敏感程度不同;该传输媒介能够传输交流电压,并随着频率的升高而升高。
A new soft optoelectronic function material, which can transmit optical and electrical signal simultaneously, was made by injecting ionic liquids (ILs) into a quartz capillary tube with the inner diameter of 0.32 mm. 10 types ILs were used to make transmission media and their characteristics were studied experimentally. It is found that optical and electrical signal can transmit respectively when the frequency of electric signal is higher than 10 Hz. The numerical aperture of the medium can achieves 0. 554, which is bigger than that of the traditional optical fiber transmission medium. The attenuation is relative to both the types of ILs and wavelengths. The impedances are sensitive to temperature, and at the same temperature the impedance disparity of different transmission media can reach more than 10 times. The maximal AC voltage that the medium can transmit increases with the increase of frequency.
