Modelling the delayed nonlinear fiber response in coherent optical communications
Daniel Semrau, Eric Sillekens, Robert I. Killey +1
Fiber nonlinearities, that lead to nonlinear signal interference (NLI), are typically regarded as an instantaneous material response with respect to the optical field. However, in…
The Benefits of Using the S-Band in Optical Fiber Communications and How to Get There
Daniel Semrau, Eric Sillekens, Robert I. Killey +1
The throughput gains of extending the optical transmission bandwidth to the S+C+L-band are quantified using a Gaussian Noise model that accounts for inter-channel stimulated Raman…
Modulation Format Dependent, Closed-Form Formula for Estimating Nonlinear Interference in S+C+L Band Systems
Daniel Semrau, Lidia Galdino, Eric Sillekens +3
A closed-form formula for the nonlinear interference estimation of arbitrary modulation formats in ultra-wideband transmission systems is presented. Enabled by the proposed approac…
Experimental Demonstration of Learned Time-Domain Digital Back-Propagation
Eric Sillekens, Wenting Yi, Daniel Semrau +9
We present the first experimental demonstration of learned time-domain digital back-propagation (DBP), in 64-GBd dual-polarization 64-QAM signal transmission over 1014 km. Performa…
Capacity increases obtained extending the transmission bandwidth in optical communication systems
Gabriel Saavedra, Daniel Semrau, Polina Bayvel
The potential benefits of extending the optical fibre transmission bandwidth are studied. Even in the presence of Kerr nonlinearity and inter-channel stimulated Raman scattering, i…
Overview and Comparison of Nonlinear Interference Modelling Approaches in Ultra-Wideband Optical Transmission Systems
Daniel Semrau, Robert I. Killey, Polina Bayvel
The recent advances in modelling nonlinear interference of systems operating beyond the C-band are discussed. Estimation accuracy as well as computational complexity of current app…
