  • Determination of the collection diffusion length by electroluminescence imaging 
    Schinke, Carsten; Hinken, David; Bothe, Karsten; Ulzhöfer, Christian; Milsted, Ashley; Schmidt, Jan; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    The electroluminescence emission of crystalline silicon solar cells at near-bandgap wavelengths is investigated. We show that the intensity of the emitted luminescence at near-bandgap wavelengths is directly proportional ...
  • Experimental setup for camera-based measurements of electrically and optically stimulated luminescence of silicon solar cells and wafers 
    Hinken, David; Schinke, Carsten; Herlufsen, Sandra; Schmidt, Arne; Bothe, Karsten; Brendel, Rolf (College Park, MD : American Institute of Physics, 2011)
    We report in detail on the luminescence imaging setup developed within the last years in our laboratory. In this setup, the luminescence emission of silicon solar cells or silicon wafers is analyzed quantitatively. Charge ...
  • Lightweight metasurface mirror of silicon nanospheres [Invited] 
    Evlyukhin, A.B.; Matiushechkina, M.; Zenin, V.A.; Heurs, Michèle; Chichko, B.N. (Washington, DC : The Optical Society, 2020)
    Many experiments in modern quantum optics require the implementation of lightweight and near-perfect reflectors for noise reduction and high sensitivity. Another important application of low mass and high reflectivity ...
  • Luminescence emission from forward- and reverse-biased multicrystalline silicon solar cells 
    Bothe, Karsten; Ramspeck, K.; Hinken, D.; Schinke, Carsten; Schmidt, J.; Herlufsen, S.; Brendel, Rolf; Bauer, J.; Wagner, J.-M.; Zakharov, N.; Breitenstein, O. (College Park, MD : American Institute of Physics, 2009)
    We study the emission of light from industrial multicrystalline silicon solar cells under forward and reverse biases. Camera-based luminescence imaging techniques and dark lock-in thermography are used to gain information ...
  • 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 ...
  • On the origin of photon mass, momentum, and energy in a dielectric medium [Invited] 
    Chichkov, Nikolai B.; Chichkov, Boris N. (Washington, DC : Optica, 2021)
    The debate and controversy concerning the momentum of light in a dielectric medium (Abraham vs Minkowski) is well-known and still not fully resolved. In this paper, we investigate the origin of both momenta in the frame ...
  • Unraveling Two-Photon Entanglement via the Squeezing Spectrum of Light Traveling through Nanofiber-Coupled Atoms 
    Hinney, Jakob; Prasad, Adarsh S.; Mahmoodian, Sahand; Hammerer, Klemens; Rauschenbeutel, Arno; Schneeweiss, Philipp; Volz, Jürgen; Schemmer, Max (College Park, Md. : APS, 2021)
    We observe that a weak guided light field transmitted through an ensemble of atoms coupled to an optical nanofiber exhibits quadrature squeezing. From the measured squeezing spectrum we gain direct access to the phase and ...
