“…In general, single channel all-optical regenerators can be achieved through in-line synchronous modulation and narrowband filtering [16][17], or they can be based on exploiting nonlinear optical gates [2][3][4][5] which might, for example, be based on an optical fiber designed and configured to exploit ultrafast nonlinear effects such as Self-Phase modulation, Cross-Phase modulation (XPM), Four-Wave mixing (FWM), or Stimulated Raman Scattering.…”

“…Several all-optical 2R (re-amplification, re-shaping) and 3R (re-amplification, re-shaping, re-timing) techniques have also been demonstrated and reported in the literature over the years [1][2][3][4] -many providing excellent regenerative performance. The vast majority of these techniques support only single optical channel operation [2][3][4][5][6][7][8], limited in terms of multichannel operation by the strong inter-channel crosstalk effects that arise when the same nonlinear medium is simultaneously used for the regeneration of all channels. However, in order for all optical regenerators to offer a commercially interesting alternative to their optoelectronic counterparts, extension to multi-channel operation is likely to be essential [9].…”

“…To date, numerous nonlinear gates have been demonstrated for regeneration, mainly based on semiconductor optical amplifiers (SOAs) [10][11][12][13], optical fibers [2][3][4][5][6][7][8], saturable absorbers [14][15], synchronous modulation associated with narrow band filtering [16][17] and electro absorption modulators (EAMs) [18][19]. However, only a few of them are truly appropriate candidates for high bit rates and high capacity WDM systems.…”

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.

“…To manage these transmission impairments, a wide variety of techniques has been proposed in terms of modulation formats, dispersion and dispersion slope compensation, PMD compensation, nonlinearity management, distributed Raman amplification scheme and forward error correction (FEC). Particularly, by incorporating 3R regeneration (retiming, reshaping, and amplification) [9]- [15] along the light paths of the optical network, the effects of optical impairments can be removed and the integrity of the data signal with regard to their timing and amplitude characteristics can be improved. 3R regeneration can be achieved in a number of methods including using optoelectronic [9] or all-optical [16] schemes.…”

This paper investigates the impact of saturable absorption (SA) on the performance of optical clock recovery using a mode-locked multisection laser diode. Optical clock at 40 GHz is recovered from the multisection laser with SA section operated under a range of bias conditions. The dependence of extinction ratio and timing jitter of the recovered clock on required optical injection power, data rate detuning, and mark ratio is also evaluated under these operation conditions. The experimental results show that strong SA effect in laser cavity improves extinction ratio and suppresses timing jitter of the recovered clock, while weak or no SA effect in laser cavity offers clock recovery with larger date rate detuning range defined by timing jitter and less dependence on the variation of data mark ratio for extremely low mark ratio.Index Terms-Data rate detuning, extinction ratio, mark ratio, multisection semiconductor laser, optical clock recovery, saturable absorption (SA), timing jitter.

“…Very promising as optical switches are the nonlinear loop mirrors, which are nonlinear Sagnac interferometers made with cross-phase modulating Kerr medium. Experimental studies at high power levels have shown that such devices can achieve very effective switching, and optical regeneration [3] up to 40 Gbit/s has been practically demonstrated [4]. The quantum characteristics of nonlinear Mach-Zehnder (or equivalently, Sagnac) interferometers have been previously investigated [5].…”
