    We have investigated the noise properties of the tunneling current through vertically coupled self-assembled InAs quantum dots. We observe super-Poissonian shot noise at low temperatures. For increased temperature this ...

    Angular misalignment of one of the interfering beams in laser interferometers can couple into the interferometric length measurement and is called tilt-to-length (TTL) coupling in the following. In the noise budget of the ...
  • Junker, J.; Wilken, D.; Huntington, E.; Heurs, Michèle (Washington, DC : The Optical Society, 2021)
    In this article, we present a novel spectroscopy technique that improves the signal-to-shot-noise ratio without the need to increase the laser power. Detrimental effects by technical noise sources are avoided by ...
  • Hohls, Frank; Maire, Niels; Kaestner, B.; Pierz, Klaus; Schumacher, Hans W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2009)
    The shot noise of a single parameter quantized charge pump is studied. The pumped current can be varied using a control gate. Quantized current plateaus / = nefp with fp the pumping frequency and e the electron charge are ...
  • Ubbelohde, Niels; Roszak, K.; Hohls, Frank; Maire, Niels; Novotný, T.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    For an InAs quantum dot we study the current shot noise at a Fermi-edge singularity in low temperature cross-correlation measurements. In the regime of the interaction effect the strong suppression of noise observed at ...
