    Opt Express 18:2884-93. 2010
    ..Theoretical results agree very well with the experimental data. The idler NF spectrum is also analyzed and measured, which shows a more symmetric profile...

    Opt Express 18:15426-39. 2010
    ..As a proof of concept, the NF of a fiber parametric amplifier based copier + PSA cascade with inter-stage attenuation representing the fiber link is measured, which shows a 1.8-dB total NF improvement over the conventional EDFA cascade...

    Z Tong
    Department of Microtechnology and Nanoscience, Chalmers University of Technology, Goteborg, Sweden
    Opt Lett 36:722-4. 2011
    ..When considering the combined NF, the optimal noise performance (0 dB NF) is obtained only when the input powers are equal. Experiments agree well with the theoretical predictions...

    Carl Lundström
    Department of Microtechnology and Nanoscience, Chalmers University of Technology, Goteborg, Sweden
    Opt Lett 36:4356-8. 2011
    ..The experimental results were obtained by imposing a linear phase modulation onto the signal and idler wave simultaneously, and detecting the input and output signal using a self-homodyne coherent receiver...
