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…
Discrete-modulation continuous-variable quantum key distribution with probabilistic amplitude shaping over a linear quantum channel
Emanuele Parente, Michele N. Notarnicola, Stefano Olivares +3
The practical implementation difficulties arising from the Gaussian modulation of the GG02 protocol lead us to investigate the possibilities offered by the combination of probabili…
Nonlinearity Compensation for Coherent Optical Satellite Communications
Stella Civelli, Luca Potì, Enrico Forestieri +1
Optical satellite uplinks rely on high-power optical amplifiers (HPOAs) to overcome free-space attenuation and enable long-distance transmission. However, at high power levels, fib…
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…
A New Twist on Low-Complexity Digital Backpropagation
Stella Civelli, Debi Pada Jana, Enrico Forestieri +1
This work proposes a novel low-complexity digital backpropagation (DBP) method, with the goal of optimizing the trade-off between backpropagation accuracy and complexity. The metho…
Coupled-Band ESSFM for Low-Complexity DBP
Stella Civelli, Debi Pada Jana, Enrico Forestieri +1
We propose a novel digital backpropagation (DBP) technique that combines perturbation theory, subband processing, and splitting ratio optimization. We obtain 0.23 dB, 0.47 dB, or 0…
