Numerical Methods for the Inverse Nonlinear Fourier Transform
Stella Civelli, Luigi Barletti, Marco Secondini
We introduce a new numerical method for the computation of the inverse nonlinear Fourier transform and compare its computational complexity and accuracy to those of other methods a…
Signal-noise interaction in nonlinear optical fibers: a hydrodynamic approach
Luigi Barletti, Marco Secondini
We present a new perturbative approach to the study of signal-noise interactions in nonlinear optical fibers. The approach is based on the hydrodynamic formulation of the nonlinear…
Quantum Communication
Nicolas Gisin
Quantum Communication is the art of transferring an unknown quantum state from one location, Alice, to a distant one, Bob. This is a non-trivial task because of the quantum no-clon…
Coherent 100G Nonlinear Compensation with Single-Step Digital Backpropagation
Marco Secondini, Simon Rommel, Francesco Fresi +3
Enhanced-SSFM digital backpropagation (DBP) is experimentally demonstrated and compared to conventional DBP. A 112 Gb/s PM-QPSK signal is transmitted over a 3200 km dispersion-unma…
Stochastic Digital Backpropagation with Residual Memory Compensation
Naga V. Irukulapati, Domenico Marsella, Pontus Johannisson +3
Stochastic digital backpropagation (SDBP) is an extension of digital backpropagation (DBP) and is based on the maximum a posteriori principle. SDBP takes into account noise from th…
