Summary:In this Chapter we review the need, general principles and approaches used to regenerate phase encoded signals of differing levels of coding complexity. We will describe the key underpinning technology and present the current state-of-the-art, incorporating an appropriate historic perspective throughout. The chapter finishes with a discussion of emerging research trends and broader future perspectives.

“…We next analyze the PSA performance limitations when operated to provide simultaneous amplitude and phase regeneration [8], [9], [20]. As we show below, the limitations arise from the fact that the amplitude regeneration requires PSA saturation which unfortunately reduces the PSA phase regeneration capability.…”

The performance of future ultra-long haul communication systems exploiting phase-encoded signals is likely to be compromised by noise generated during signal transmission. One potential way to mitigate such noise is to use Phase Sensitive Amplifiers (PSAs) which have been demonstrated to help remove phase as well as amplitude noise from phaseencoded signals. Recently, we showed that a PSA-based signal regenerator based on degenerate four-wave mixing can be implemented in a network-compatible manner in which only the (noisy) signal is present at the device input (black-box operation). The developed regenerator was also able to perform simultaneous wavelength conversion and multicasting, details/analysis of which are presented herein. However, this scheme was tested only with artificial noise generated in the laboratory and with the regenerator placed in front of the receiver, rather than in-line where even greater performance benefits are to be expected. Here, we address both theoretically and experimentally the important issue of how such a regenerator, operating for convenience in a multicasting mode, performs as an in-line device in an installed transmission fiber link. We also investigate the dispersion tolerance of the approach.

“…There are several reasons for this, including their ability to provide phase-sensitive amplification [1][2][3], multicasting [4], regeneration [3,[5][6][7] and wavelength conversion [8,9]. It is noted that especially when applying the FOPA as an amplifier or regenerator, most emphasis has been on single-pumped amplifiers.…”
