We investigate both experimentally and theoretically the interaction between a light beam and a photonic lattice optically induced with partially coherent light. We demonstrate a clear transition from two-dimensional discrete diffraction to discrete solitons in such a partially coherent lattice and show that the nonlinear interaction process is associated with a host of new phenomena including lattice dislocation, lattice deformation, and creation of structures akin to optical polarons.
我们通过实验和理论研究了光束与由部分相干光光学诱导产生的光子晶格之间的相互作用。我们证明了在这种部分相干晶格中从二维离散衍射到离散孤子的清晰转变,并表明非线性相互作用过程伴随着许多新现象,包括晶格位错、晶格变形以及类似于光学极化子的结构的产生。
