TL;DR: In this article, a fiber-based quasi-soliton-like pulse is proposed to propagate quasi-solons, which allows significantly improved transmission property by reducing much of the intrinsic problems of solitons.

TL;DR: In this article, the authors proposed a field-coupling model for propagation in graded-index multimode fiber (MMF), analogous to the principal states model for polarization-mode dispersion (PMD) in single-mode fiber.
Abstract: Previously, we proposed a field-coupling model for propagation in graded-index multimode fiber (MMF), analogous to the principal states model for polarization-mode dispersion (PMD) in single-mode fiber. That model was based on the concept of first-order principal modes, which have well-defined group delays that depend on the strength of the mode coupling. That first-order model predicts a linear relationship between the intensity waveforms at the MMF input and output. Here, we extend that model to account for higher order modal dispersion. The higher-order model predicts several effects analogous to higher-order PMD: pulse broadening, filling-in between peaks of the pulse response, depolarization and pattern blurring at the MMF output, and a nonlinear relationship between input and output intensity waveforms.

TL;DR: In this paper, a mode-division-multiplexed system using coherent detection using strong mode coupling is presented. But the authors do not consider the effect of coherent detection on the mode-dependent gain of optical amplifiers.
Abstract: In mode-division-multiplexed systems using coherent detection, strong mode coupling is beneficial. Mode coupling reduces modal dispersion, minimizing signal processing complexity. In combination with modal dispersion, mode coupling creates frequency diversity, mitigating the mode-dependent gain of optical amplifiers.

TL;DR: In this article, a simple and accurate approximation of modal dispersion in single-mode optical fibres deduced from spectral behaviour of mode spot size is presented. But neither knowledge of index profile nor of maximum refractive index difference are required in this approximation.

TL;DR: In this paper, the impact of polarization mode dispersion on long distance IM-DD systems was analyzed both theoretically and experimentally by means of a 2.5 Gb/s synchronous digital hierarchy (SDH) commercial system.
Abstract: Polarization mode dispersion can influence long distance IM-DD systems especially when optical amplifiers are used to increase the unrepeated link length. The impact of this phenomenon is analyzed in this letter both theoretically and experimentally by means of a 2.5 Gb/s synchronous digital hierarchy (SDH) commercial system. Polarization dispersion has a nonnegligible impact on the system performance when the associated differential group delay is of the order of 100 ps. >
