Photonic lattices, arrays of evanescently coupled waveguides written by femtosecond laser, are often used to control the flow of light. Two cases are here considered experimentally. i) In the linear regime, a faithful transfer is achieved when the photonic structure is judiciously designed. ii) In the nonlinear regime, we show that photonic lattices support a new type of laser filaments, called lattice filaments, with controllable attributes.
