Frequency combs have the potential to be used as multi-wavelength sources in future optical communications through fiber. Here the authors demonstrate joint phase processing of multi-wavelength comb transmission, and show two schemes to improve perfo

We experimentally investigate a wavelength-division multiplexing (WDM) system with a single span of 80 km standard single-mode fiber (SSMF) and a phase-sensitive amplifier (PSA) as a pre-amplifier. Using two channels spaced 25 GHz apart with single-p

We report on the development of a $2\times 800$ Gbps/wave coherent module based on a monolithic InP transceiver PIC and real-time 7nm DSP ASIC capable of 800Gbps data transmission over record 1000km SMF-28 link using a 96Gbaud, PCS-64QAM modulation f

We show that the transmission reach increase with phase-sensitive amplifiers (PSAs) compared to phase-insensitive amplifiers is significantly enhanced for higher-order modulation formats in single-channel, single-span transmission experiments.

This paper investigates the use of optoelectronic subsystems placed all the way along a fiber link to provide distributed mitigation of the distortion caused by the Kerr nonlinearity. These subsystems use power-dependent phase modulation to mitigate

The throughput and reach in fiber-optic communication links are limited by in-line optical amplifier noise and the Kerr nonlinearity in the optical transmission fiber. Phase-sensitive amplifiers (PSAs) are capable of amplifying signals without adding

We experimentally demonstrate, for the first time, cross-phase modulation (XPM) compensation using an optical phase modulator and low-bandwidth electronics. We first show that our nonlinearity compensator suppresses the XPM distortion from a 10-Gb/s

We propose an optoelectronic method for the distributed compensation of nonlinear fiber distortions affecting polarization multiplexed signals. This method involves placing devices we call total-intensity-directed phase modulators at the start of eac

We investigate combining phase-sensitive optical amplifiers (PSAs) with a static Volterra nonlinear equalizer (VNLE) to mitigate residual nonlinear distortions. Experiments show that the VNLE reduces penalties from link design and improves QBER by 0.

We demonstrate the use of in-line low-noise phase-sensitive amplifiers (PSAs) in a wavelength-division multiplexing long-haul transmission link with a recirculating loop experiment. We quantify how replacing phase-insensitive amplifiers with PSAs can
