Nondegenerate Bright Solitons in Coupled Nonlinear Schrödinger Systems: Recent Developments on Optical Vector Solitons

Nonlinear dynamics of an optical pulse or a beam continue to be one the active areas research in field solitons. Especially, multi-mode fibers fiber arrays and photorefractive materials, vector solitons display rich nonlinear phenomena. Due their fascinating intriguing novel properties, theory has been developed considerably both from theoretical experimental points view leading soliton-based promising potential applications. Mathematically, can understood framework coupled Schrödinger (CNLS) family equations. In recent past, many types have identified integrable non-integrable CNLS framework. this article, we review some progress understanding so called nondegenerate bright optics, where fundamental soliton more than propagation constant. We address theme by considering two equations, namely Manakov system, mixed 2-CNLS system (or focusing-defocusing system), coherently (CCNLS) generalized (GCNLS) two-component long-wave short-wave resonance interaction (LSRI) system. these models, discuss existence associated multi-hump geometrical profile nature deriving analytical forms through Hirota bilinear method. Then reveal collision properties as example. The asymptotic analysis shows that solitons, general, undergo three elastic collisions without any energy redistribution among modes. Furthermore, show sharing exhibiting arises special case newly reported Finally, point out possible further developments subject
