我们描述了一种基于Teflon AF 2400毛细管的液芯光纤，Teflon AF 2400是一种透明的无定形含氟聚合物，折射率为1.29。当填充几乎任何透明液体时，光纤能够通过全内反射传输光。对于250 μ m-i. d.，在可见光区的大部分区域内，损耗低于3 dB/m。纤维充满水。该装置在增强芯液的拉曼光谱强度方面的实用性得到了证明。(C)1997年，美国光学学会。
We describe a liquid-core optical fiber based on capillary tubing of Teflon AF 2400, which is a clear, amorphous fluoropolymer having a refractive index of 1.29. When filled with virtually any transparent liquid, the fiber is capable of transmitting Light by total internal reflection. Loss below 3 dB/m is demonstrated throughout much of the visible region for a 250-mu m-i.d. fiber filled with water. The utility of this device in enhancing the intensity of Raman spectra of core liquids is demonstrated. (C) 1997 Optical Society of America.
