“…The first experimental realization of a frequency-nondegenerate PSA-amplified transmission link was using single-channel 2.5 Gbit/s non-return-to-zero (NRZ) data transmitted over a 60 km dispersion compensated link [9]. The frequency-and phase-locking of the waves was accomplished using an optical double-sideband modulation scheme [10,11], with the bandwidth limited to the bandwidth of the optical modulators used to generate the sidebands.…”

“…In [9] the pump recovery before the PSA was achieved using a single EDFA and possible penalty due to pump degradation through the pump recovery was not considered. As mentioned earlier, the experimental work presented in [5,15,16] was carried out with a lumped signal/idler loss instead of transmission link and thus no pump attenuation stage or pump recovery system was used or required in those demonstrations.…”

Abstract:An injection locking-based pump recovery system for phase-sensitive amplified links, capable of handling 40 dB effective span loss, is demonstrated. Measurements with 10 GBd DQPSK signals show penalty-free recovery of a pump wave, phase modulated with two sinusoidal RF-tones at 0.1 GHz and 0.3 GHz, with 64 dB amplification. The operating power limit for the pump recovery system is experimentally investigated and is governed by the noise transfer and phase modulation transfer characteristics of the injection-locked laser. The corresponding link penalties are explained and quantified. This system enables, for the first time, WDM compatible phase-sensitive amplified links over significant lengths.

“…The effects of PMD on channel capacity of coherent fibre optic systems were investigated by (Goebel et al 2007). Moreover, work has also focussed on phase-sensitive parametric amplifiers (Tang et al 2005) and dispersion maps (Fischer et al 2006). Based on an increasingly focussed research trend on fibre optic network protocols, speed and quality optimisation techniques, it can be ascertained that the fibre optic communication domain is very likely to gain further improvement in near future.…”

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.
