Wavelength-division multiplexing (WDM) has historically enabled the increase in the
capacity of optical systems by progressively populating the existing optical bandwidth 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 …

This report presents a comprehensive approach to dispersion management, including
various techniques, mathematical analysis, and their advantages and disadvantages in …

We investigate quality of transmission (QoT) estimation in a multi-band transmission
scenario, including a wideband description of the frequency-dependent physical layer …

We report on a new record in the field of broadband BDFA in the O+ E spectral range. Using
only 250 mW single wavelength pump at 1256 nm and a low-OH bismuth-doped fiber …

We report for the first time an ultra-wideband coherent (UWB) WDM transmission over a 70
km standard single mode fibre (SSMF) solely using a multistage discrete Raman amplifier …

In this paper, we show that by combining experimental data from different optical fibers, we
can build a fiber-agnostic neural-network to model the Raman amplifier. The fiber-agnostic …

The problem of Raman amplifier optimization is studied. A differentiable interpolation
function is obtained for the Raman gain coefficient using machine learning (ML), which …

We investigate the impact of stimulated Raman scattering (SRS) in multi-band
transmissions. We first derive and test against numerical results an extended …

Optical communication systems are always evolving to support the need for ever–increasing
transmission rates. This demand is supported by the growth in complexity of communication …
