  • Dispersion-engineered multi-pass cell for single-stage post-compression of an ytterbium laser 
    Silletti, Laura; bin Wahid, Ammar; Escoto, Esmerando; Balla, Prannay; Rajhans, Supriya; Horn, Katinka; Winkelmann, Lutz; Wanie, Vincent; Trabattoni, Andrea; Heyl, Christoph M.; Calegari, Francesca (Washington, DC : Soc., 2023)
    Post-compression methods for ultrafast laser pulses typically face challenging limitations, including saturation effects and temporal pulse breakup, when large compression factors and broad bandwidths are targeted. To ...
  • Entwurfskonzept einer Car2Car-Multiband-Dachantenne 
    Wang, Yuanhao; Reit, Marco; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2012)
    Due to the vastly increasing use of wireless services in the car, such as WiFi, Car2Car and LTE, the requirements on bandwidth and radiation pattern of the roof antenna systems become more challenging. In this work, a ...
  • A low-power, low-noise 37-MHz photoreceiver for intersatellite laser interferometers using discrete heterojunction bipolar transistors 
    Barranco, German Fernandez; Sheard, Benjamin S.; Dahl, Christian; Mathis, Wolfgang; Heinzel, Gerhard (Piscataway, NJ : Institute of Electrical and Electronics Engineers Inc., 2018)
    Intersatellite laser interferometers feature quadrant photoreceivers to produce electrical signals from the interfered optical beams. In the particular case of LISA, the expected optical AC beat note has an amplitude of ...
  • Manufacturing and characterization of asymmetric evanescent field polished couplers for grating assisted mode selective fiber coupling 
    Schlangen, Sebastian; Bremer, Kort; Zheng, Yulong; Isaak, Andreas; Wurz, Marc Christopher; Böhm, Sebastian; Wellmann, Felix; Steinke, Michael; Pelegrina Bonilla, Gabriel; Neumann, Jörg; Kracht, Dietmar; Roth, Bernhard; Overmeyer, Ludger (Bellingham, Wash. : SPIE, 2018)
    Mode division multiplexing (MDM) could bring a technological progress in the field of optical telecommunication by increasing the data transmission bandwidth. A key challenge for enabling MDM lies in manufacturing of ...
  • Preparing attosecond coherences by strong-field ionization 
    Pabst, Stefan; Lein, Manfred; Wörner, Hans Jakob (College Park, MD : American Physical Society, 2016)
    Strong-field ionization (SFI) has been shown to prepare wave packets with few-femtosecond periods. Here, we explore whether this technique can be extended to the attosecond time scale. We introduce an intuitive model, which ...
  • Squeezed States of Light for Future Gravitational Wave Detectors at a Wavelength of 1550 nm 
    Meylahn, Fabian; Willke, Benno; Vahlbruch, Henning (College Park, Md. : APS, 2022)
    The generation of strongly squeezed vacuum states of light is a key technology for future ground-based gravitational wave detectors (GWDs) to reach sensitivities beyond their quantum noise limit. For some proposed observatory ...
  • Ultrahigh bandwidth spin noise spectroscopy: Detection of large g-factor fluctuations in highly-n-doped GaAs 
    Berski, Fabian; Kuhn, Hendrik; Lonnemann, Jan G.; Hübner, Jens; Oestreich, Michael (College Park, MD : American Physical Society, 2013)
    We advance all optical spin noise spectroscopy (SNS) in semiconductors to detection bandwidths of several hundred gigahertz by employing a sophisticated scheme of pulse trains from ultrafast laser oscillators as an optical ...
