Research on Dipole Solitons in Optically Induced Lattices
Photonic lattices are optically induced in photorefractive crystals and the transmission of dipole solitons in photonic lattices is studied. By means of numerical simulation, when the dipole beams are launched at the diagonal lattice sites, different transmission results of dipole beams are obtained when the intensity of bias field voltage, the intensity of beams and the depth of lattices are changed. These results show that the input dipole beams can overcome the interaction between the two humps as a result of the existence of the lattices. Under suitable conditions, out-of-phase dipole solitons exist and are stable. In contrast, in-phase dipole solitons are always instable, and the instability is weaker if the beam intensity is lower.
