Journal ArticleDOI
Statistical treatment of the evolution of the principal states of polarization in single-mode fibers
TL;DR: In this article, a simple relationship for the evolution of the principal states of polarization (PSPs) and their differential group delay in fiber links is found, using the relationship, for the probability of DGD.
Journal ArticleDOI
Polarization modulated direct detection optical transmission systems
TL;DR: In this article, a novel polarization modulated direct detection (PM-DD) system for binary and multilevel transmission is presented. But the system performance is evaluated by an analytical model when the only relevant noise source is the receiver thermal noise and when erbium-doped optical amplifiers introduce amplified spontaneous emission (ASE) noise.
Journal ArticleDOI
A novel multilevel coherent optical system: 4-quadrature signaling
TL;DR: In this article, a multilevel coherent optical system is proposed based on the property that the electromagnetic field propagating in a single-mode optical fiber can be represented by a four-dimensional vector whose components are the phase and quadrature terms of the two polarization components of the electrical field.
Journal ArticleDOI
Multilevel coherent optical system based on Stokes parameters modulation
TL;DR: In this paper, a multilevel transmission system that allows efficient exploitation of a single-channel bandwidth in coherent optical communication systems is proposed based on Stokes parameter modulation and a decision on the Poincare sphere.
Journal ArticleDOI
Phase noise and polarization state insensitive optical coherent systems
TL;DR: In this paper, three different schemes that allow compensation of phase noise and polarisation state change by sending a reference channel that is suitably frequency shifted by using polarization modulation together with Stokes parameters detection or computing and inverting the Jones matrix that describes the fiber polarization state transformation are presented.
