Abstract

There is growing interest in the refractive index of liquids beyond the visible and into the short-wave infrared (SWIR) for applications such as the study of liquid-core fibers and supercontinuum generation. However, most of the data reported are in the visible. For liquids with a wide transmission window in the SWIR region, refractive index data are sparse. We present a Rayleigh interferometry-based refractometer to characterize the refractive index relative to standard materials at seven different wavelengths (543.4, 632.8, 780, 973, 1064, 1550, and 1970 nm) at a temperature of ~ 21.3 ± 0.6 °C. We also show Sellmeier fits using our results juxtaposed with previously published data. Our data extends previous work to the SWIR.

利用瑞利干涉仪测量 0.5 至 2 µm 范围内液体的折射率

人们对液体折射率的研究兴趣日益浓厚，已超出了可见光的范围，进入了短波红外（SWIR），用于研究液芯光纤和超连续发生等应用。然而，报告的大部分数据都是可见光数据。对于在 SWIR 区域具有宽透射窗口的液体，折射率数据非常稀少。我们介绍了一种基于瑞利干涉仪的折射仪，用于表征在 ~ 21.3 ± 0.6 °C 温度下七个不同波长（543.4、632.8、780、973、1064、1550 和 1970 nm）相对于标准材料的折射率。我们还展示了利用我们的结果与以前发表的数据并列进行的 Sellmeier 拟合。我们的数据将以前的工作扩展到了西南红外波段。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
