Two-component solitons under a spatially modulated linear coupling: Inverted photonic crystals and fused couplers
Two-component solitons spatially modulated linear Inverted photonic crystals fused couplers Optics
2012/5/29
We study two-component solitons and their symmetry-breaking bifurcations (SBBs) in linearly coupled photonic systems with a spatially inhomogeneous strength of the coupling. One system models an inver...
Elimination of transverse instability in stripe solitons by one-dimensional lattices
Elimination of transverse stripe solitons one-dimensional lattices Optics
2012/5/28
We demonstrate theoretically and experimentally that the transverse instability of coherent soliton stripes can be greatly suppressed or totally eliminated when the soliton stripes propagate in a one-...
Controlled absorption and all-optical diode action due to collisions of self-induced transparency solitons
Controlled absorption all-optical diode action collisions of self-induced transparency solitons Optics
2012/4/20
We study inelastic collisions of counter-propagating self-induced transparency solitons in a homogeneously broadened two-level medium. The energy of the pulse can be almost totally absorbed in the med...
Dynamics of optomechanical spatial solitons in dual-nanoweb structures
Dynamics of optomechanical spatial solitons dual-nanoweb structures Optics
2012/4/20
We theoretically investigate the stability and dynamics of self-channelled beams that form via nonlocal optomechanical interactions in dual-nanoweb microstructured fibers. These "optomechanicons" repr...
Linear superpositions of gap solitons in periodic Kerr media
Linear superpositions gap solitons periodic Kerr media
2011/8/3
Abstract: The existence of a novel type of solitons in periodic Kerr media constructed as superposition of noninteracting gap-solitons of different kinds (bright, dark and periodic) is first demonstra...

Defect Solitons PT Symmetric Optical lattices nonlocal nonlinearity
2011/8/3
Abstract: The existence and stability of defect solitons in parity-time (PT) symmetric optical lattices with nonlocal nonlinearity are reported. Fundamental solitons are found in the semi-infinite gap...

Solitons complex PT symmetric Gaussian potentials Optics
2011/8/2
Abstract: The existence and stability of fundamental, dipole, and tripole solitons in Kerr nonlinear media with parity-time (PT) symmetric Gaussian complex potentials are reported. Fundamental soliton...
A refined empirical stability criterion for nonlinear Schroedinger solitons under spatiotemporal forcing
Schroedinger solitons
2011/9/29
We investigate the dynamics of travelling oscillating solitons of the cubic NLS equation under an external spatiotemporal forcing of the form f(x, t) = a exp[iK(t)x].For the case of time-independent f...
Solitons in thermal media with periodic modulation of linear refractive index
thermal media periodic modulation linear refractive index
2011/9/6
We address the existence and the properties of solitons in thermal media with periodic distribution of two different linear refractive indices. Many kinds of
solitons in such optical lattices, includ...
Fundamental solitons pinned to the interface between three semi-infinite one-dimensional nonlinear dynamical chains, coupled at a single site, are investigated. The light propagation in the respective...
