液体填充的光子晶体光纤和光流控器件需要渗透各种液体，这些液体的线性光学特性在宽光谱范围内（特别是在近红外区域）仍然不为人所知。因此，在 20 摄氏度的温度下，测定了蒸馏水、重水、氯仿、四氯化碳、甲苯、乙醇、二硫化碳和硝基苯在可见光和近红外波长区域的色散和吸收特性。对于折射率测量，使用标准阿贝折射计与白光激光和计算技术相结合 使用了校正项来补偿玻璃棱镜的色散。 500 nm 和 1600 nm 波长之间的新折射率数据和推导的色散公式与该波长范围内稀疏的现有参考数据非常一致。吸收系数是根据几个相同制备的液体填充玻璃池或不同长度的管的损耗差异推导出来的。我们提供 500 nm 至 1750 nm 波长范围内的吸收数据。 (C) 2012年美国光学学会
Liquid-filled photonic crystal fibers and optofluidic devices require infiltration with a variety of liquids whose linear optical properties are still not well known over a broad spectral range, particularly in the near infrared. Hence, dispersion and absorption properties in the visible and near-infrared wavelength region have been determined for distilled water, heavy water, chloroform, carbon tetrachloride, toluene, ethanol, carbon disulfide, and nitrobenzene at a temperature of 20 degrees C. For the refractive index measurement a standard Abbe refractometer in combination with a white light laser and a technique to calculate correction terms to compensate for the dispersion of the glass prism has been used. New refractive index data and derived dispersion formulas between a wavelength of 500 nm and 1600 nm are presented in good agreement with sparsely existing reference data in this wavelength range. The absorption coefficient has been deduced from the difference of the losses of several identically prepared liquid filled glass cells or tubes of different lengths. We present absorption data in the wavelength region between 500 nm and 1750 nm. (C) 2012 Optical Society of America
