Based on density functional theory with the generalized gradient approximation plus on-site Coulomb repulsion method, we study the magnetic-ordering dependence of second-harmonic generation (SHG) in a polar magnet BiCoO(3). The large second-order optical susceptibility, which can reach 3.7x10(-7) esu, exhibits a strong magnetic-ordering dependence, giving rise to magnetic-field controllable SHG...

It is shown that mutual trapping of the fundamental and second-harmonic waves in a dispersive medium with quadratic nonlinearity supports a variety of solitary waves including bright and dark solitons, solitons with trapped radiation, stable bound states of two (or more) solitons. The results are demonstrated for parametric interactions in optical ,$*I materials but can be generalized to other ...
