    • Bipolar photodiode module operated at 4 K 

      Bardalen, Eivind; Nissilä, Jaani; Fordell, Thomas; Karlsen, Bjørnar; Kieler, Oliver; Øhlckers, Per (Chapter, 2020)
      An optoelectronic module for generating high frequency bipolar current pulses at 4 K was developed. Bipolar signals are generated by connecting a pair of photodiodes in series to coplanar waveguides on silicon. The ...

    • High-Speed Pulsation of a Cryogenically Operable Bipolar Photodiode Module for the Josephson Arbitrary Waveform Synthesizer 

      Karlsen, Bjørnar; Bardalen, Eivind; Nissilä, Jaani; Fordell, Thomas; Kieler, Oliver; Palafox, Luis; Behr, Ralf; Malmbekk, Helge; Akram, Muhammad Nadeem; Øhlckers, Per (Peer reviewed; Journal article, 2020)
      This paper describes the development and testing of a prototype of a cryogenically operable bipolar photodiode module. Optical pulsation systems based on both a Mach-Zehnder modulator and a mode-locked laser have been used ...
