چکیده
The paper studies the dynamics of degenerate and nondegenerate bright solitons their collisions in two-component nonlinear Schrödinger equations coupled to Boussinesq equation. that have only single-hump profiles, exhibit both elastic inelastic collisions, velocities are identical two short wave (SW) components long (LW) component. single different forms: one them has double- or profiles all SW LW components, other admits unequal components. cannot result redistribution soliton intensities. Three types two-soliton solutions studied detail.

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Unstaggered-staggered solitons in two-component discrete nonlinear Schrödinger lattices.
We present stable bright solitons built of coupled unstaggered and staggered components in a symmetric system of two discrete nonlinear Schrödinger equations with the attractive self-phase-modulation nonlinearity, coupled by the repulsive cross-phase-modulation interaction. These mixed modes are of a "symbiotic" type, as each component in isolation may only carry ordinary unstaggered solitons. ...

We investigate numerically the collision dynamics of elliptically polarized solitons of the System of Coupled Nonlinear chrödinger Equations (SCNLSE) for various different initial polarizations and phases. General initial elliptic polarizations (not ech-shape) include as particular cases the circular and linear polarizations. The elliptically polarized solitons are computed by separate numerica...
متن کاملCollisions of two solitons in an arbitrary number of coupled nonlinear Schrödinger equations.
We show that pairwise soliton collisions in N>2 intensity-coupled nonlinear Schrödinger equations can be reduced to pairwise soliton collisions in two coupled equations. The reduction applies to a wide class of systems, including the N-component Manakov system. This greatly simplifies the analysis of such systems and has important implications for the application of soliton collisions to all-op...
