title: Discrete temporal solitons along a chain of nonlinear coupled microcavities embedded in photonic crystals.
abstract: We demonstrate that spatiotemporal discrete solitons are possible in nonlinear photonic crystal structures. Analysis indicates that these states can propagate undistorted along a series of coupled resonators or defects by balancing of the effects of discrete lattice dispersion with material nonlinearity. In principle, these self-localized entities are capable of exhibiting very low velocities, depending on the coupling coefficient among successive microcavities. This class of solitons can follow any preassigned path in a three-dimensional environment.
