Fiber nonlinearity has become a major limiting transmission impairment factor. In this paper,
we discuss various nonlinearity mitigation techniques in electrical and optical domains. In …

An optical remodulator includes: a polarization diversity modulator configured to modulate
an input optical signal to generate an output optical signal by using a first optical modulator …

We propose optical injection locking (OIL) to enable compensation of the inter-channel
nonlinear phase noise, which is dominated by cross-phase modulation (XPM). In this paper …

We propose an optoelectronic method for the distributed compensation of nonlinear fiber
distortions affecting polarization multiplexed signals. This method involves placing devices …

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 …

We experimentally demonstrate, for the first time, cross-phase modulation (XPM)
compensation using an optical phase modulator and low-bandwidth electronics. We first …

We review our progress in using few-gigahertz-bandwidth optoelectronic circuits to
compensate for cross-phase modulation between widely spaced WDM channels. This …

In the dense wavelength-division multiplexing (DWDM)-based 5G fronthaul network, cross-
phase modulation (XPM) would become more obvious to degrade the signal when the …

We demonstrate in-line nonlinearity compensation (NLC) of a 5-channel dual-polarization
16-QAM signal using opto-electronic sub-systems called total intensity-directed phase …

This paper has dealt with the mitigation effect of cross-phase modulation (XPM) which is a
nonlinear effect of fiber losses. To control the losses, we have used a quantum dot vertical …
