“…The benefits of the spectral compression occurring upon pulse propagation in a dispersive-nonlinear regime [15,16] in terms of enhanced opening of a signal eye pattern could also be explored. Using time interleaving, the scheme should be suitable for multi-wavelength operation [37,38]. It can also potentially be compatible with a simultaneous processing of the state of polarization of a signal [39].…”

Abstract:We numerically study the effects of amplitude fluctuations and signal-to-noise ratio degradation of the seed pulses on the spectral compression process arising from nonlinear propagation in an optical fibre. The unveiled quite good stability of the process against these pulse degradation factors is assessed in the context of optical regeneration of intensity-modulated signals, by combining nonlinear spectral compression with centered bandpass optical filtering.The results show that the proposed nonlinear processing scheme indeed achieves mitigation of the signal's amplitude noise. However, in the presence of a jitter of the temporal duration of the pulses, the performance of the device deteriorates.

“…Finally, in a third approach, which has been developed for WDM OOK signals, carefully engineered dispersive walkthrough maps in fibers are used to avoid the inter-channel crosstalk [30,[33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]. In these schemes a high local average dispersion value ensures that the nonlinear inter-channel effects are significantly weaker due to the fast walk-off time among the various WDM channels, while a low overall average dispersion value ensures that the nonlinear effect used for the regeneration process itself (SPM) is sufficiently retained, Fig.1 (c).…”

“…It is, though, worth pointing out that, to date, SPM-based regenerators are the most promising ones due to their simple implementation and excellent performance and thus the easiest to be adapted for multi-wavelength operation if OOK signals are used. These types of SPM-based regenerators differ in their architectures, according to whether the various WDM channels all propagate in the same direction [30,[33][34][35][36][37][38][39][40][41] or some in opposite directions [42][43][44][45][46][47][48] within the nonlinear fiber, see Fig. 1 (c.i-v).…”

Abstract-Multi-wavelength all-optical regeneration has the potential to substantially increase both the capacity and scalability of future optical networks. In this paper we review recent promising developments in this area. First we recall the basic principles of multi-channel regeneration of high bit rate signals in optical communication systems before discussing the current technological approaches. We then describe in detail two fiber-based multi-channel 2R regeneration techniques for RZ-OOK based on (a) dispersion managed systems and (b) direction and polarization multiplexing. We present results illustrating the levels of performance so far achieved and discuss various practical issues and prospects for further performance enhancement.Index Terms-Nonlinear optical, devices; Kerr effect; signal regeneration; nonlinear optical signal processing; ultrafast processes in fibers.

“…On the other hand, multi-wavelength regeneration has been demonstrated to date only for on-off keying (OOK) signal formats [4]. The proposed techniques achieved amplitude noise suppression simultaneously on multiple channels either through soliton compression techniques [11], [12], or through redesign of the Mamyshev's regenerator employing carefully engineered dispersive walk-through maps to minimize the crosstalk of neighboring channels [14] [15].…”

Future high capacity optical links will have to make use of frequent signal regeneration to enable long distance transmission. In this respect, the role of all-optical signal processing becomes increasingly important because of its potential to mitigate signal impairments at low cost and power consumption. More substantial benefits are expected if regeneration is achieved simultaneously on a multiple signal band. Until recently, this had been achieved only for on-off keying modulation formats. However, as in future transmission links the information will be encoded also in the phase for enhancing the spectral efficiency, novel subsystem concepts will be needed for multichannel processing of such advanced signal formats. In this paper we show that phase sensitive amplifiers can be an ideal technology platform for developing such regenerators and we discuss our recent demonstration of the first multi-channel regenerator for phase encoded signals.
