Different discrete soliton states in periodic optical induced waveguide lattice.
Different discrete soliton states in optical waveguide lattices are studied theoretically for the different external conditions such as the biased field, lattice spacing and the position of the input pulse. It is demonstrated that the discrete solitons can be formed in an appropriate biased field and exhibit different discrete properties in different biased field. The results also indicate that lattice spacing and the position of input pulse can affect apparently the discreteness of discrete solitons. If changing the ratio of the waist width of input beam to lattice period, the discrete solitons will be excited in more or less channels. In addition, the increase of lattice intensity almost does not affect the propagation behavior of soliton.
