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 …

In this paper, we provide an overview of recent progress on advanced digital signal
processing (DSP) techniques for high-capacity long-haul coherent optical fiber transmission …

Digital coherent receivers have caused a revolution in the design of optical transmission
systems, due to the subsystems and algorithms embedded within such a receiver. After …

Optical OFDM was proposed for dispersion compensation in long-haul optical
communications systems in 2006 in two forms, one using direct-detection and the other …

Digital backpropagation (BP) is a universal method for jointly compensating dispersion and
nonlinear impairments in optical fiber and is applicable to signals of any modulation format …

Backpropagation has been shown to be the most effective method for compensating intra-
channel fiber nonlinearity in long-haul optical communications systems. However, effective …

By the means of reconstructing the Darboux transformation to the Manakov system, we
obtain the new explicit solutions composed of a rogue wave and a breather for the system …

Using multimode fibers for long-haul transmission is proposed and demonstrated
experimentally. In particular few-mode fibers (FMFs) are demonstrated as a good …

This work proposes a probabilistic sha** scheme for optical WDM systems, where
nonlinear interference noise depends on the input optical signal power distribution. With …

Next-generation optical communication systems will continue to push the (bandwidth·
distance) product towards its physical limit. To address this enormous demand, the usage of …
