文摘

We show that pyroelectric spatial solitons can exist in non-photovoltaic photorefractive crystals under open-circuit conditions due to excellent pyroelectric effects. The space-charge field induced by pyroelectric fields is deduced by considering the boundary condition of divergenceless current. Moreover, the solution of bright, dark, and gray solitons is obtained by solving the solitary wave equation and the related numerical results are given.
