  • Extended measurement setup for transient TEM waveguide characterization 
    Briest, Niklas; Garbe, Heyno; Potthast, S. (Göttingen : Copernicus GmbH, 2016)
    This paper discusses a field measurement method, based on a two-antenna setup, to qualify the transmission of transient signals inside a GTEM cell. The transmission characteristic of the GTEM1250 is evaluated by the Pearson ...
  • High power, single-frequency, monolithic fiber amplifier for the next generation of gravitational wave detectors 
    Wellmann, Felix; Steinke, Michael; Meylahn, Fabian; Bode, Nina; Willke, Benno; Overmeyer, Ludger; Neumann, Jörg; Kracht, Dietmar (Washington, DC : OSA - The Optical Society, 2019)
    Low noise, high power single-frequency lasers and amplifiers are key components of interferometric gravitational wave detectors. One way to increase the detector sensitivity is to increase the power injected into the ...
  • Matrix heater in the gravitational wave observatory GEO 600 
    Wittel, H.; Affeldt, Christoph; Bisht, A.; Doravari, S.; Grote, Hartmut; Lough, J.; Lück, Harald; Schreiber, E.; Strain, K.A.; Danzmann, Karsten (Washington, DC : Optical Society of America, 2018)
    Large scale laser interferometric gravitational wave detectors (GWDs), such as GEO 600 require high quality optics to reach their design sensitivity. The inevitable surface imperfections, inhomogeneities, and light-absorption ...
  • Optical fibre sensors based on multi-mode fibres and MIMO signal processing: An experimental approach 
    Ahrens, Andreas; Sandmann, Andre; Bremer, Kort; Roth, Bernhard; Lochmann, Steffen (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    In this paper multiple-input multiple-output (MIMO) signal processing is investigated for fibre optic sensor applications. A (2 × 2) MIMO implementation is realized by using lower-order and higher-order mode groups of a ...
