Towards integration of a liquid-filled fiber capillary for mid-IR supercontinuum generation — •Stefan Kedenburg, Timo Gissibl, Tobias Steinle, Andy Steinmann, and Harald Giessen — 4th Physics Institute and Research Center SCoPE, University of Stuttgart, Germany

We demonstrate supercontinuum generation in unspliced as well as in integrated CS2-filled capillary fibers at pump wavelengths of 1030 nm, 1510 nm, and 1685 nm. A novel method for splicing the liquid-filled capillary fiber to a standard single-mode optical fiber is presented. This method is based on mechanical splicing. 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 μm and 10 μm, 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.
