TL;DR: The development of the first practical ('black-box') all-optical regenerator capable of removing both phase and amplitude noise from binary phase-encoded optical communications signals is reported.

TL;DR: In this paper, an optical-fiber-based non-degenerate PSA link consisting of a phase-insensitive parametric copier followed by a PSA that provides broadband amplification, signal modulation format independence, and nearly 6dB link noise-figure (NF) improvement over conventional, erbium-doped fiber amplifier based links.

TL;DR: In this paper, a copier-PSA scheme is proposed, which consists of a parametric phase-insensitive copier followed by one or more PSAs, and a record-low 1.1 dB noise figure was measured at >;26 dB gain.

TL;DR: A single-pumped, non-degenerate phase-sensitive parametric amplifier with a precise control of phase and amplitude of the in-going waves is experimentally demonstrated and a departure from the theoretical maximum attenuation as the gain increases is observed and explained.

TL;DR: In this article, the authors investigate the properties of transmission links amplified by phase-sensitive amplifiers (PSAs) and show that in a link with standard single mode fiber (SSMF) the optimum dispersion map for efficient nonlinearity mitigation corresponds to precompensation of an amount equal to the effective loss length.
