Performance Optimization of Short Reach Optical Interconnects based on Direct Detection
Luca Poì, Stella Civelli, Marco Secondini +11
Short-reach optical interconnects are evolving toward data rates beyond 400 Gb/s per lane, driven by the bandwidth and energy-efficiency requirements of AI-enabled datacenter netwo…
Regular Perturbation on the Group-Velocity Dispersion Parameter for Dual-Polarization Short-Reach Systems
Dario Cellini, Vinícius Oliari, Erik Agrell +3
The Manakov equation governs the propagation of signals in dual-polarization systems. Its solution is usually approximated by regular perturbation on the nonlinear Kerr parameter.…
ML-Enhanced Digital Backpropagation for Long-Reach Single-Span Systems
Dario Cellini, Stella Civelli, Marco Secondini
We propose a digital backpropagation method that employs machine-learning-aided joint optimization of dispersion step lengths and nonlinear phase rotation filters within an FFT-bas…
Fiber Nonlinearity Mitigation in Coherent Optical Systems
Stella Civelli, Dario Cellini, Enrico Forestieri +1
Fiber nonlinearity represents a critical challenge to the capacity enhancement of modern optical communication systems. In recent years, significant research efforts have focused o…
