Stabilization of vector soliton complexes in nonlocal nonlinear media.

چکیده
We introduce vector soliton complexes in nonlocal Kerr-type nonlinear media. We discover that under proper conditions the combination of nonlocality and vectorial coupling has a remarkable stabilizing action on multihumped solitons. In particular, we find that stable bound states featuring several field oscillations in each soliton component do exist. This affords stabilization of vector soliton trains incorporating a large number of humps, a class of structures known to self-destroy via strong instabilities in scalar settings.

Spiraling solitons and multipole localized modes in nonlocal nonlinear media
We analyze the propagation of rotating multi-soliton localized structures in optical media with spatially nonlocal nonlinearity. We demonstrate that nonlocality stabilizes the azimuthal breakup of rotating dipole as well as multipole localized soliton modes. We compare the results for two different models of nonlocal nonlinearity and suggest that the stabilization mechanism is a generic propert...
متن کاملDark-bright soliton pairs in nonlocal nonlinear media.
We study the formation of dark-bright vector soliton pairs in nonlocal Kerr-type nonlinear medium. We show, by analytical analysis and direct numerical calculation, that in addition to stabilize of vector soliton pairs nonlocal nonlinearity also helps to reduce the threshold power for forming a guided bright soliton. With help of the nonlocality, it is expected that the observation of dark-brig...
متن کاملCollapse arrest and soliton stabilization in nonlocal nonlinear media.
We investigate the properties of localized waves in cubic nonlinear materials with a symmetric nonlocal nonlinear response of arbitrary shape and degree of nonlocality, described by a general nonlocal nonlinear Schrödinger type equation. We prove rigorously by bounding the Hamiltonian that nonlocality of the nonlinearity prevents collapse in, e.g., Bose-Einstein condensates and optical Kerr med...

Recently increased interest in the study of self-trapped optical beams in nonlocal nonlinear media is explained by experimental observations of nonlocal spatial solitons in liquid crystals and lead glasses as well as a number of many interesting theoretical predictions, including stabilization of vortex solitons against symmetry breaking instability in the media with nonlocal optical response. ...
متن کاملSoliton transverse instabilities in nonlocal nonlinear media
We analyze the transverse instabilities of spatial bright solitons in nonlocal nonlinear media, both analytically and numerically. We demonstrate that the nonlocal nonlinear response leads to a dramatic suppression of the transverse instability of the soliton stripes, and we derive the asymptotic expressions for the instability growth rate in both shortand long-wave approximations. c © 2008 Opt...
