“…On the other hand, since the concept of polarization attraction is based on a general FWM counter-propagating interaction, the device could also be extended to other physical parameters providing an equivalent system of equations for instance attraction between two spatial propagation modes or wavelengths [33,44]. The device could include another function such as Raman amplification [45] (also compatible with Mamyshev regenerator [46]), phase regeneration and/or pulse-topulse retiming [23,47]. Finally, based on these observations, we believe that this new type of 3R device, combining three critical telecommunication functions (Repolarization, Reshaping,…”

In this paper, we report all-optical regeneration of the state of polarization of a 40-Gbit/s return-to-zero telecommunication signal as well as its temporal intensity profile and average power thanks to an easy-to-implement, all-fibered device. In particular, we experimentally demonstrate that it is possible to obtain simultaneously polarization stabilization and intensity profile regeneration of a degraded light beam thanks to the combined effects of counterpropagating four-wave mixing, self-phase modulation and normal chromatic dispersion taking place in a single segment of optical fiber. All-optical regeneration is confirmed by means of polarization and bit-error-rate measurements as well as real-time observation of the 40 Gbit/s telecommunication signal.

“…An implementation of the similariton-based regeneration technique at 40 Gbit/s data rate where similariton pulses are generated through distributed Raman amplification in a ND fibre is illustrated in Figures 5(b) and 5(c). It is worth noting here that a distributed amplification is helpful in increasing the energy yield of the regenerator which is a highly dissipative element [102].…”

The development of new all-optical technologies for data processing and signal manipulation is a field of growing importance with a strong potential for numerous applications in diverse areas of modern science. Nonlinear phenomena occurring in optical fibres have many attractive features and great, but not yet fully explored, potential in signal processing. Here, we review recent progress on the use of fibre nonlinearities for the generation and shaping of optical pulses and on the applications of advanced pulse shapes in all-optical signal processing. Amongst other topics, we will discuss ultrahigh repetition rate pulse sources, the generation of parabolic shaped pulses in active and passive fibres, the generation of pulses with triangular temporal profiles, and coherent supercontinuum sources. The signal processing applications will span optical regeneration, linear distortion compensation, optical decision at the receiver in optical communication systems, spectral and temporal signal doubling, and frequency conversion.

“…The goal is here to evaluate the impact of a co-propagating pumping scheme on a discrete Raman amplifier that may be used in the context of new telecommunications windows that cannot benefit from standard erbium doped fibre technologies [45,46] or in the context of applications that require broad gain bandwidths [47]. Raman amplification can also be exploited to reinforce some nonlinear processings carried out in highly nonlinear elements [48][49][50]. In order to limit the consequences of pump depletion and gain saturation, we have used an initial peak-power of 5 mW, i.e.…”

“…Such a proportion is not affected by the level of initial input power so that even for much lower average input powers, similar degradations are observed. With such a penalty, co-propagating pumping scheme has to be banned in Raman-enhanced optical regenerators [48][49][50]. As a direct consequence, it seems hard to combine the advantages of a bidirectional setup such as in [52,53] with the benefits of Raman amplification.…”
