Abstract:
It is shown that bright-dark Manakov solitons can be formed in biased guest-host photorefractive polymer when the total intensity of two components is much lower than the background illumination.The existing conditions of bright-dark Manakov solitons are discussed in detail.The intensity profiles and dynamical evolutions of solitons are presented by numerical methods.
