We propose spatiotemporal solitons that consist of trains of short pulses. The pulses are collectively trapped in the transversal directions by a slow nonlinearity and each pulse is self-trapped temporally by a fast nonlinearity.
We present a novel type of stable (3+1)D solitary self-trapped wave-packet arising from the interplay between local and nonlocal (in time and space) nonlinearities, which can be generated under experimentally feasible conditions.
Beyond the well known breathing of dispersion-managed solitons, a long-period oscillation has been reported. We identify the origin of this oscillation: These solitons are composite objects; the constituents can beat with each other.
We present a perturbation theory explaining the interaction of adjacent dispersion managed solitons. A stable equilibrium separation and oscillations around it are found. The model is validated by comparison to experimental and numerical results.
We demonstrate theoretically the existence of polariton-solitons in semiconductor microcavity in the strong-coupling regime. Their relaxation time and required pump powers are at list one order less than those of their weakly coupled light-only counterparts.
We investigate spatio-temporal focusing of an elliptically-shaped beam in a bulk mediumwith a Kerr nonlinearity and anomalous dispersion. Strong spatio-temporal localization of the mode is observed via multi-filamentation and temporal compression.
