Fully localized two-dimensional embedded solitons
نویسنده
چکیده
We report the prediction of fully localized two-dimensional embedded solitons. These solitons are obtained in a quasi-one-dimensional waveguide array which is periodic along one spatial direction and localized along the orthogonal direction. Under appropriate nonlinearity, these solitons are found to exist inside the Bloch bands (continuous spectrum) of the waveguide and thus are embedded solitons. These embedded solitons are fully localized along both spatial directions. In addition, they are fully stable under perturbations.

Two-photon cavity solitons in active optical media.
We show that broad-area cascade lasers with no absorbing intracavity elements support the spontaneous formation of two-dimensional bright localized structures in a dark background. These cavity solitons consist of islands of two-photon emission embedded in a background of single-photon emission. We discuss the mechanisms through which these structures are formed and interact, along with their p...
متن کاملConfined dissipative droplet solitons in spin-valve nanowires with perpendicular magnetic anisotropy.
Magnetic dissipative droplets are localized, strongly nonlinear dynamical modes excited in nanocontact spin valves with perpendicular magnetic anisotropy. These modes find potential application in nanoscale structures for magnetic storage and computation, but dissipative droplet studies have so far been limited to extended thin films. Here, numerical and asymptotic analyses are used to demonstr...
متن کاملAdjustable Plasmonic Bandgap in One-Dimensional Nanograting Based on Localized and Propagating Surface Plasmons
Compared to the long history of plasmonic gratings, there are only a few studies regarding the bandgap in the propagation of plasmonic surface waves. Considering the previous studies on interpretation of plasmonic bandgap formation, we discuss this phenomenon using the effect of both surface plasmon polariton (SPP) and localized surface plasmon (LSP) for our fabricated one-dimensional metallic-...
متن کاملTwo–Dimensional Magnetic Solitons and Thermodynamics of Quasi–Two–Dimensional Magnets
The article reviews two–dimensional magnetic solitons in a classical weakly– anisotropic Heisenberg magnets. Topological classification, structure, dynamical properties and thermodynamical contribution of 2D solitons to response functions of the magnet are discussed. On the basis of taking in the paper effective equations of motion we calculated the soliton contribution to the dynamical structu...
متن کاملExperimental evidence of dissipative spatial solitons in an optical passive Kerr cavity
We report on the first experimental evidence of localized structures (dissipative solitons) in a one-dimensional optical Fabry–Pérot passive Kerr cavity. The Kerr-like medium is a non-instantaneous, diffusive ultra-thin film of liquid crystal inserted in a low-finesse cavity. Solitons with oscillating tails are experimentally observed in this system that can lock together to form complexes of s...
