“…All-optical modulation format conversion might become a necessary technology for future all-optical networks, which may employ miscellaneous formats. Various alloptical format converters between RZ and NRZ including NOLMs [113] and SOAs [114,115] have been demonstrated in back-to-back schemes. Here, we describe a novel transmission technique based on periodic in-line all-optical format conversion between RZ and NRZ-like [83].…”

All-optical data processing is expected to play a major role in future optical communications. The fiber nonlinear optical loop mirror (NOLM) is a valuable tool in optical signal processing applications. This paper presents an overview of our recent advances in developing NOLM-based all-optical processing techniques for application in fiber-optic communications. The use of in-line NOLMs as a general technique for all-optical passive 2R (reamplification, reshaping) regeneration of return-to-zero (RZ) on-off keyed signals in both high-speed, ultralong-distance transmission systems and terrestrial photonic networks is reviewed. In this context, a theoretical model enabling the description of the stable propagation of carrier pulses with periodic all-optical self-regeneration in fiber systems with in-line deployment of nonlinear optical devices is presented. A novel, simple pulse processing scheme using nonlinear broadening in normal dispersion fiber and loop mirror intensity filtering is described, and its employment is demonstrated as an optical decision element at a RZ receiver as well as an in-line device to realize a transmission technique of periodic all-optical RZ-non-return-to-zero-like format conversion. The important issue of phase-preserving regeneration of phase-encoded signals is also addressed by presenting a new design of NOLM based on distributed Raman amplification in the loop fiber.

“…Various techniques have been proposed and demonstrated to realize both 2R (reamplification, reshaping) and 3R (including retiming) regenerators. The regenerative medium can be either passive optical fiber [1] or active components such as distributed feedback (DFB) lasers, electro-absorption modulators, and semiconductor optical amplifiers (SOAs) [2]- [5]. The scheme based on an electro-absorption modulator with crossabsorption modulation effect has been tested up to 40 Gb/s [3].…”

“…The all-optical solution provides a much higher processing speed, provides transparency, and mitigates the optoelectronic conversion bottleneck. All-optical functions that have been developed include switching [1][2][3] header processing [4,5], buffering methods [6][7][8][9], wavelength conversion [10][11][12] signal regeneration [13], and limited signal processing used for high-speed transmission such as multiplexing and demultiplexing [14][15][16], and for logic functions [17,18].…”

This paper considers the performance of an alloptical packet-switched cross-connect. All-optical header processing and all-optical routing are implemented in the cross-connect architectures. The main metric considered to measure the performance is the packet loss ratio for the buffering. This is influenced primarily by three factors. The first is the cross-connect architecture: feedback or feed-forward buffering, incorporating wavelength domain contention resolution. The second is the selection of the fibre delay line distribution: degenerate or non-degenerate distributions. And the third is the traffic load together with the traffic model used for the performance analysis: a Poisson distribution or a selfsimilar model. It is shown that the optimal implementation of a feedback buffer requires a technique such as overflow buffering as well as the superior performance of an all-optical switch in order to maintain signal quality through multiple recirculations.
