   Suppression of Spurious Mixing in FWM-Based Systems Through Mid-Span Pump Phase Shift

   Presenter: Kyle Bottrill, University of Southampton

    Presentation Details   Paper

   We propose and demonstrate a new technique to suppress spurious idler generation during four-wave mixing, by applying a π radian phase shift to the pumps at the mid-point of the processing medium.Authors: Kyle Bottrill, University of Southampton / Natsupa Taengnoi, University of Southampton / Hao Liu, University of Southampton / Ravikiran Kakarla, University of Southampton / Yang Hong, University of Southampton / Periklis Petropoulos, University of Southampton

   Ultralow-Loss Silicon Nitride Waveguides for Parametric Amplification

   Presenter: Victor Torres Company, Chalmers Tekniska Högskola

    Presentation Details   Paper

   Invited

   We report net gain in a continuous-wave-pumped parametric amplifier implemented in a meter-long dispersion-engineered silicon nitride waveguide. These results are enabled by the record-low loss (1.4dB/m) of the waveguide.Authors: Victor Torres Company, Chalmers Tekniska Högskola / Zhichao Ye, Chalmers Tekniska Högskola / Ping Zhao, Chalmers Tekniska Högskola / Magnus Karlsson, Chalmers Tekniska Högskola / Peter Andrekson, Chalmers Tekniska Högskola

   Hybrid Amplification Approach to Communications Beyond C- and L-Bands

   Presenter: Youichi Akasaka, Fujitsu Network Communications Inc

    Presentation Details   Paper

   Invited

   This report introduces novel techniques to amplify new bandwidths rather than C- and L-band by utilizing advantages of each amplification phenomena such as high power efficiency and flexible bandwidth to overcome each of its drawback.Authors: Youichi Akasaka, Fujitsu Network Communications Inc

   Power Consumption and FWM Crosstalk Analysis of a Hybrid S-Band Abased on Two Parametric Wavelength Converters and an EDFA

   Presenter: Cheng Guo, University of Texas at Arlington

    Presentation Details   Paper

   We measure and analyze the power efficiency and four-wave-mixing crosstalk of a hybrid S-band amplifier based on parametric wavelength converters and EDFA at input signal levels from –30 to –20 dBm/ch and 20-dB gain.Authors: Cheng Guo, University of Texas at Arlington / Michael Vasilyev, University of Texas at Arlington / Youichi Akasaka, Fujitsu Network Communications / Paparao Palacharla, Fujitsu Network Communications
