Optical communication systems represent the backbone of modern communication
networks. Since their deployment, different fiber technologies have been used to deal with …

Nonlinear optical response of silica imposes a fundamental limit on the information transfer
capacity in optical fibers. Communication beyond this limit requires higher signal power and …

In this paper, we review the historical evolution of predictions of the performance of optical
communication systems. We will describe how such predictions were made from the outset …

Coherent optical orthogonal frequency division multiplexing (CO-OFDM) has attracted a lot
of interest in optical fiber communications due to its simplified digital signal processing …

We explore the potential benefits of digital nonlinearity compensation (NLC) techniques in
fully loaded coherent wavelength-division multiplexed (WDM) transmission systems. After …

In this paper, we experimentally demonstrate the benefit of polarization insensitive dual-
band optical phase conjugation for up to ten 400 Gb/s optical super-channels using a …

In this paper, we demonstrate through computer simulation and experiment a novel
subcarrier coding scheme combined with pre-electrical dispersion compensation (pre-EDC) …

We investigate a time-domain implementation of generalized phase-conjugated twin waves
which we call conjugate data repetition. A theory based on time-domain perturbation …

In this paper, we demonstrate a novel fiber nonlinearity compensation technique for
coherent optical orthogonal frequency-division multiplexing (CO-OFDM) systems based on …

We discuss recent progress on the use of optical and digital phase conjugation techniques
for nonlinearity compensation in optical fiber links. We compare the achievable performance …
