Model-Based Machine Learning for Joint Digital Backpropagation and PMD Compensation

Christian Häger, Henry D. Pfister, Rick M. Bütler et al.

We propose a model-based machine-learning approach for polarization-multiplexed systems by parameterizing the split-step method for the Manakov-PMD equation. This approach performs hardware-friendly DBP and distributed PMD compensation with performance close to the PMD-free case.

Revisiting Multi-Step Nonlinearity Compensation with Machine Learning

Christian Häger, Henry D. Pfister, Rick M. Bütler et al.

For the efficient compensation of fiber nonlinearity, one of the guiding principles appears to be: fewer steps are better and more efficient. We challenge this assumption and show that carefully designed multi-step approaches can lead to better performance-complexity trade-offs than their few-step counterparts.
