    "abstract": "We address the formation and propagation of multi-spot soliton packets in\nsaturable Kerr nonlinear media with an imprinted harmonic transverse modulation\nof the refractive index. We show that, in sharp contrast to homogeneous media\nwhere stable multi-peaked solitons do not exist, the photonic lattices support\nstable higher-order structures in the form of soliton packets, or soliton\ntrains. Intuitively, such trains can be viewed as made of several lowest order\nsolitons bound together with appropriate relative phases and their existence as\nstable objects puts forward the concept of compact manipulation of several\nsolitons as a single entity.",
