Realizing the effect of soliton interaction with third order dispersion (TOD) in 100 Gbps telecommunication system
01 Nov 2014-pp 1-6
TL;DR: In this article, the effect of third order dispersion (TOD) on in-phase soliton interaction with and without TOD in a 100Gbps telecommunication system was studied.
Abstract: In this work, we study the effect of in-phase soliton interaction with and without the effect of third order dispersion (TOD) in 100Gbps telecommunication system The relative spacing of soliton is chosen as 528 (qo) and their interaction is noted in one collision period or length (Lcoll) The soliton interaction without TOD is noted with β2=−255ps2/Km and with TOD near Zero Dispersion (ZD) point of −022ps2/Km The effect of TOD decreases the interaction effect when noted with TOD value of β3=001 ps3/Km and further there was no interaction with high value of β3=01 ps3/Km The main characteristic of TOD causing temporal shifts is noted in in-phase solitons where the higher deviation is noted with β3=01 ps3/Km than β3=001 ps3/Km Further, we have also examined the effect of TOD with 3 and 6 solitons pulses to note the interaction effect Finally it could be seen that when more than 2 soliton pulses are launched, TOD would degrade the system performance, where these adjacent pulses cross each other due to temporal shifts

TL;DR: Theoretical calculations supported by numerical simulations show that utilization of the nonlinear dependence of the index of refraction on intensity makes possible the transmission of picosecond optical pulses without distortion in dielectric fiber waveguides with group velocity dispersion.
Abstract: Theoretical calculations supported by numerical simulations show that utilization of the nonlinear dependence of the index of refraction on intensity makes possible the transmission of picosecond optical pulses without distortion in dielectric fiber waveguides with group velocity dispersion. In the case of anomalous dispersion (∂2ω/∂k2>0) discussed here [the case of normal dispersion (∂2ω/∂k2<0) will be discussed in a succeeding letter], the stationary pulse is a ``bright'' pulse, or envelope soliton. For a typical glass fiber guide, the balancing power required to produce a stationary 1‐ps pulse is approximately 1 W. Numerical simulations show that above a certain threshold power level such pulses are stable under the influence of small perturbations, large perturbations, white noise, or absorption.

TL;DR: In this paper, the authors reported narrowing and splitting of 7-ps-duration pulses from a mode-locked color-center laser by a 700m-long, singlemode silica-glass fiber, at a wavelength (1.55 \ensuremath{mu}m) of loss and large but negative group-velocity dispersion.
Abstract: This paper reports narrowing and splitting of 7-ps-duration pulses from a mode-locked color-center laser by a 700-m-long, single-mode silica-glass fiber, at a wavelength (1.55 \ensuremath{\mu}m) of loss and large but negative group-velocity dispersion. At certain critical power levels, the observed behavior is characteristic of solitons.

TL;DR: The state of knowledge on spatial soliton interactions is reviewed and effects such as fusion, fission, annihilation, and stable orbiting in three dimensions are reviewed.
Abstract: Spatial solitons, beams that do not spread owing to diffraction when they propagate, have been demonstrated to exist by virtue of a variety of nonlinear self-trapping mechanisms. Despite the diversity of these mechanisms, many of the features of soliton interactions and collisions are universal. Spatial solitons exhibit a richness of phenomena not found with temporal solitons in fibers, including effects such as fusion, fission, annihilation, and stable orbiting in three dimensions. Here the current state of knowledge on spatial soliton interactions is reviewed.

TL;DR: In this paper, the history of the use of solitons for optical fiber communications and the technical developments toward making soliton transmission practical are reviewed and the causes of bit errors in long-distance soliton transmissions are presented and the methods for reducing them are described.
Abstract: The history of the proposal that solitons be used for optical fiber communications and of the technical developments toward making soliton transmission practical is reviewed. The causes of bit errors in long-distance soliton transmission are presented and the methods for reducing them are described. A perturbation theory suited for soliton analysis is developed. Current status and future prospects of long-distance repeaterless fiber communications are stated.
