Experimental Validation of Sequence-Wise Predistorter for Evaluation of Geometrically Shaped 128-QAM
Menno van den Hout, Sjoerd van der Heide, Sebastiaan Goossens +1
A predistorter for transmitter nonlinearities is applied to the evaluation of a geometrically shaped constellation, such that constellation points are transmitted correctly during…
Optical Field Characterization using Off-axis Digital Holography
Sjoerd van der Heide, Bram van Esch, Menno van den Hout +10
Angular resolved digital holography is presented as a technique for real-time characterization of the full optical field (amplitude and phase) of space-division multiplexing compon…
Mitigating Nonlinear Interference by Limiting Energy Variations in Sphere Shaping
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
Band-trellis enumerative sphere shaping is proposed to decrease the energy variations in channel input sequences. Against sphere shaping, 0.74 dB SNR gain and up to 9% increase in…
Kurtosis-limited Sphere Shaping for Nonlinear Interference Noise Reduction in Optical Channels
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
Nonlinear interference (NLI) generated during the propagation of an optical waveform through the fiber depends on the fourth order standardized moment of the channel input distribu…
Field Trial of a Flexible Real-time Software-defined GPU-based Optical Receiver
Sjoerd van der Heide, Ruben S. Luis, Benjamin J. Puttnam +6
We introduce a flexible, software-defined real-time multi-modulation format receiver implemented on an off-the-shelf general-purpose graphics processing unit (GPU). The flexible re…
1 Tbit/s/ Transmission Over a 130 km Link Consisting of Graded-Index 50 m Core Multi-Mode Fiber and 6LP Few-Mode Fiber
Menno van den Hout, Sjoerd van der Heide, John van Weerdenburg +7
We demonstrate 1 Tbit/s/ single-span transmission over a heterogeneous link consisting of graded-index 50 m core multi-mode fiber and 6LP few-mode fiber using a Kramers-Kroni…
