  • Frequency feedback for two-photon interference from separate quantum dots 
    Zopf, Michael; Macha, Tobias; Keil, Robert; Urunuela, Eduardo; Chen, Yan; Alt, Wolfgang; Ratschbacher, Lothar; Ding, Fei; Meschede, Dieter; Schmidt, Oliver G. (College Park : American Physical Society, 2018)
    We employ active feedback to stabilize the frequency of single photons emitted by two separate quantum dots to an atomic standard. The transmission of a rubidium-based Faraday filter serves as the error signal for frequency ...
  • On the maximum damping performance of piezoelectric switching techniques 
    Neubauer, Marcus; Han, Xu; Wallaschek, Jörg (London : SAGE Publications Ltd., 2013)
    Synchronized switch damping on inductor offers a high damping performance in a broad frequency range. It consists of an inductor and resistor in a serial configuration, which are connected and disconnected from the ...
  • Optimal design of piezoelectric actuators for shunt damping techniques 
    Neubauer, Marcus (Warsaw : Polish Academy of Sciences, Institute of Fundamental Technological Research, 2014)
    In vibration control with piezoceramics, a high coupling of the piezoelement with the structure is desired. A high coupling improves the damping performance of passive techniques like shunt damping. The coupling can be ...
  • Piezoelectric screening in single InAs/AlAs quantum dots 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Meyer, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Institute of Physics, 2009)
    Micro-photoluminescence spectroscopy for varying temperature, excitation intensity and energy was performed on a single InAs/AlAs self-assembled quantum dot. A broad sideband at 1.2 meV of the zero phonon line is attributed ...
  • Temperature-dependent coercive field measured by a quantum dot strain gauge 
    Chen, Yan; Zhang, Yang; Keil, Robert; Zopf, Michael; Ding, Fei; Schmidt, Oliver G. (Washington : American Chemical Society, 2017)
    Coercive fields of piezoelectric materials can be strongly influenced by environmental temperature. We investigate this influence using a hetero-structure consisting of a single crystal piezoelectric film and a quantum ...
