摘要： We show that incoherently coupled grey－grey spatial soliton pairs can be established in guest－host photorefractive polymers under steady-state conditions, provided that their carrier beams have the same polarization, wavelength, and are mutually incoherent. The properties of these soliton pairs, such as their width and polarization, are discussed in detail.
