The last few years have seen a wealth of new nonlinear propagation modeling results
appear in the literature, especially regarding coherent systems operating in the absence of …

In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most
cost-efficient and thus the main driver for capacity increase for decades. As a result, the …

Several approximate non-linear fiber propagation models have been proposed over the
years. Recent re-consideration and extension of earlier modeling efforts has led to the …

This paper is devoted to an in-depth discussion of the Gaussian Noise (GN) model which
describes non-linear propagation in uncompensated coherent transmission systems. Similar …

Digital coherent transceivers have revolutionized optical fiber communications due to their
superior performance offered compared to intensity modulation and direct detection based …

An accurate, closed-form expression evaluating the nonlinear interference (NLI) power in
coherent optical transmission systems in the presence of inter-channel stimulated Raman …

We study the properties of nonlinear interference noise (NLIN) in fiber-optic communications
systems with large accumulated dispersion. Our focus is on settling the discrepancy …

The nonlinear Fourier transform (NFT), a powerful tool in soliton theory and exactly solvable
models, is a method for solving integrable partial differential equations governing wave …

Networking technologies are fast evolving to support the request for ubiquitous Internet
access that is becoming a fundamental need for the modern and inclusive society, with a …
