Soliton communication beyond the average-soliton regime
We study semianalytically soliton dynamics in a soliton-based communication line for which the amplifier spacing is larger than the soliton period (referred to as the quasi-adiabatic regime). This regime allows us to overcome the limit on the soliton duration (TFWHM , 15 ps) imposed by the average-soliton regime. Our calculations show that periodically stable propagation of short solitons (TFWH...
متن کاملPolarization scattering by soliton-soliton collisions.
We have discovered experimentally that soliton-soliton collisions in wavelength division multiplexing significantly alter the polarization states of the colliding solitons. Analysis shows that the change in polarization is according to the cross product of the Stokes vectors of the colliding solitons. Birefringence of the fiber spans can turn this polarization scattering into a significant sour...
متن کاملPolarization scattering by soliton-soliton collisions
Collision of two solitons of the Manakov system is studied analytically. Existence of a complete polarization mode switching regime is proved and the parameters of solitons prepared for polarization switching are found. The idea of an analytical approach to the description of polarized (i.e., vector) solitons in nonlinear optical fibers is based on the fact [1] that for some values of the param...
متن کاملSome traveling wave solutions of soliton family
Solitons are ubiquitous and exist in almost every area from sky to bottom. For solitons to appear, the relevant equation of motion must be nonlinear. In the present study, we deal with the Korteweg-deVries (KdV), Modied Korteweg-de Vries (mKdV) and Regularised LongWave (RLW) equations using Homotopy Perturbation method (HPM). The algorithm makes use of the HPM to determine the initial expansion...
متن کاملSheep Soliton
Monitoring small groups of sheep in spontaneous evolution in the field, we decipher behavioral rules that sheep follow at the individual scale in order to sustain collective motion. Individuals alternate grazing mode at null speed and moving mode at walking speed, so cohesive motion stems from synchronizing when they decide to switch between the two modes. We propose a model for the individual ...
