我们证明了在未拼接以及在集成CS2填充的毛细管光纤在不同的泵浦波长为1030 nm，1510 nm和1685 nm的超连续产生。提出了一种将充液毛细管光纤与标准单模光纤拼接的新方法。该方法基于使用飞秒双光子聚合过程的直接激光写入聚合物套圈的机械拼接。尽管充满液体的毛细管具有多模能力，但我们主要保持单模操作。产生的超连续谱表现出超过1200 nm和1000 nm的光谱宽度为5 μ m和10 μ m的核心直径，分别。这是一个超过50%的增加相比，以前在文献中报道的值，由于改善分散性能的毛细管。(C)2015美国光学学会
We demonstrate supercontinuum generation in unspliced as well as in integrated CS2-filled capillary fibers at different pump wavelengths of 1030 nm, 1510 nm, and 1685 nm. A novel method for splicing a liquid-filled capillary fiber to a standard single-mode optical fiber is presented. This method is based on mechanical splicing using a direct-laser written polymer ferrule using a femtosecond two-photon polymerization process. We maintain mostly single-mode operation despite the multi-mode capability of the liquid-filled capillaries. The generated supercontinua exhibit a spectral width of over 1200 nm and 1000 nm for core diameters of 5 mu m and 10 mu m, respectively. This is an increase of more than 50 percent compared to previously reported values in the literature due to improved dispersion properties of the capillaries. (C) 2015 Optical Society of America
