The existence and stability of incoherently coupled bright–dark soliton families in photorefractive polymers

Abstract

It is shown theoretically that incoherently coupled bright-dark soliton families can be realized in biased guest-host photorefractive polymers under steady-state conditions. The numerical results show that the soliton families exist irrespective of the polarization of the incident optical beams and that they are stable only in the state of x-polarization.

Bright-Dark Manakov Solitons in Biased Guest-Host Photorefractive Polymer

“…2 and 4, we can conclude that the bright-dark Manakov soliton is stable in spite of the polarization of solitary wave, which is different from the high intensity. [18] The reason is that the low intensity soliton is always stable at a certain range. [19] Furthermore, we give fifteen percent intensity perturbation to solitons profiles in Fig.…”

“…(4a) to a set of equations containing the N components and studied them via the numerical methods to depict the intensity profiles of the dark and bright soliton families with three or two components. Reference [21] has extended Eqs. (4) to a set of equations governing the incoherently-coupled spatial bright-dark soliton families, and the numerical analysis indicates that the soliton families exist irrespective of the polarization of incident optical beams.…”
