Optical networks form the backbone of modern communications and the Internet and with
the ever increasing popularity of video streaming and other high bandwidth applications to …

New customer usages such as on-demand high-definition videos, business analytics, and
cloud services stress more and more optical transport networks. While 100 Gbps WDM …

This thesis describes substantial advances in the physical layer modelling of optical fibre
communication systems in the nonlinear regime. Optical communication networks are …

In this paper we report on the details of the derivation of approximate closed-form results
related to the coherence effect in non-linear noise accumulation, in the context of the GN …

A detailed theoretical study is conducted on the nonlinear interference in the same-
wavelength bidirectional coherent optical fiber communication systems. The Gaussian noise …

The GN-model appears as the convergent result of many parallel perturbative approaches.
Further investigation is needed to better identify its limitations. Analytical extensions and …

A new, fast, and simple methodology for optimizing the launch parameters in a long-haul
dispersion-managed links is proposed. With this new, simple method, it is possible to quickly …
