Popis: In the bias photovoltaic-photorefractive crystal, the two-component nonlinear Schrödinger equation can portray the dynamics of periodic wave pair and photovoltaic soliton pair. These excitations are analytically revealed including the Jacobian sn-cn type and sn-dn type periodic wave pair and their related dark-bright soliton pair, the mixed elliptic function pair excitation and their related bi-peaked soliton and bright soliton pair. In view of these results, the formation conditions of these periodic wave and soliton pairs are related to parameters of the photovoltaic field, the space charge electric field, irradiance and nonlinearity. Moreover, the excitation regulation of soliton pairs including amplitudes, widths and the change of propagation constants based on the parameter related to the photovoltaic field and space charge electric field is investigated in the bias photovoltaic-photorefractive LiNbO3crystal.
