Anisotropic photonic lattices and discrete solitons in photorefractive media

Terhalle, Bernd; Desyatnikov, Anton S; Bersch, C; Trager, D; Tang, L; Imbrock, Jorg; Denz, Cornelia; Kivshar, Yuri


We study experimentally two-dimensional periodic photonic lattices optically imprinted in photorefractive nonlinear media, and explore the effect of anisotropy on the induced refractive-index patterns. The orientation anisotropy is demonstrated by comparing square and diamond lattices, while the polarization anisotropy is shown to distinguish ordinarily and extraordinarily polarized light. In particular, the extraordinarily polarized lattice induces much stronger refractive-index modulation for...[Show more]
