Nondegenerate bright solitons in coupled nonlinear Schrödinger systems: Recent developments on optical vector solitons

S. Stalin, R. Ramakrishnan, M. Lakshmanan

Nonlinear dynamics of an optical pulse or a beam continue to be one of the active areas of research in the field of optical solitons. Especially, in multi-mode fibers or fiber arra…

Multihumped nondegenerate fundamental bright solitons in -coupled nonlinear Schrödinger system

R. Ramakrishnan, S. Stalin, M. Lakshmanan

In this letter we report the existence of nondegenerate fundamental bright soliton solution for coupled multi-component nonlinear Schrödinger equations of Manakov type. To derive t…

Nondegenerate Solitons and their Collisions in Manakov System

R. Ramakrishnan, S. Stalin, M. Lakshmanan

Recently, we have shown that the Manakov equation can admit a more general class of nondegenerate vector solitons, which can undergo collision without any intensity redistribution…

Nondegenerate soliton solutions in certain coupled nonlinear Schrödinger systems

S. Stalin, R. Ramakrishnan, M. Lakshmanan

In this paper, we report a more general class of nondegenerate soliton solutions, associated with two distinct wave numbers in different modes, for a certain class of physically im…

Nondegenerate solitons in Manakov system

S. Stalin, R. Ramakrishnan, M. Senthilvelan +1

It is known that Manakov equation which describes wave propagation in two mode optical fibers, photorefractive materials, etc. can admit solitons which allow energy redistribution…
