• Absorption Measurements in Liquid Core Waveguides Using Cavity 

      Bescherer, Klaus; Barnes, Jack A.; Loock, Hans-Peter (2016-03-07)
      Short liquid core waveguides (LCWs) were included into a fiber-loop cavity ring-down absorption spectrometer to reduce the detection limit over, both, single pass absorption in a LCW and cavityenhanced absorption using a ...
    • Fabrication and Modeling of Multimode Fiber Lenses 

      Bescherer, Klaus; Munzke, Dorit; Oliver Reich, Oliver; Loock, Hans-Peter (2016-03-07)
      We report on the fabrication, modeling, and experimental verification of the emission of fiber lenses fabricated on multimode fibers in different media. Concave fiber lenses with a radius of 150 μm were fabricated onto a ...
