Conventional optical coherent receivers capture the full electrical field, including amplitude
and phase, of a signal waveform by measuring its interference against a stable continuous …

The Kramers-Kronig (KK) receiver has recently drawn a great deal of attention due to its
capability of retrieving the phase information from the directly-detected intensity waveforms …

Increased global traffic puts tough requirements not just on fiber communications links but
on the entire network. This manifests itself in multiple ways, including how to optimize …

The performance of coherent optical systems can be seriously degraded when in-phase and
quadrature (IQ) components experience misalignments crossing certain critical limits. The …

The periodically poled LiNbO 3 (PPLN) based optical parametric amplifier (OPA) is a
technology that contributes to the construction of multi-band wavelength-division …

By using a modified particle swarm optimization (M-PSO) design, a novel and blind
modulation format identification (MFI) scheme was proposed for elastic optical networks …

Dispersion compensation is the most important feature required in optical fiber
communication system because absence of it leads to pulse spreading that causes the …

In the coherent long-reach passive optical networks (LRPON), it is crucial to propose cost-
effective digital signal processing (DSP) technologies to reduce the overall complexity and …

This paper proposes a parametric network for the joint compensation of multiple linear
impairments in coherent optical communication systems. The considered linear impairments …

This paper considers Godard's error as signal quality metric to monitor chromatic dispersion
(CD), nonlinear parameter and modulation format in the DSP module of the coherent …
