We demonstrate that optical solitons can exist in dispersion-inverted highly-nonlinear AlGaAs nanowires. These self-localized waves are possible at very low power levels in millimeter long nanowire structures.
We report the first experimental observation of discrete quadratic interface solitons existing at the edge of a PPLN waveguide array. Both in-phase and staggered discrete surface solitons were observed.
We show that the giant Kerr nonlinearity in the regime of electromagnetically induced transparency in vapor can give rise to the formation of Thirring-type spatial solitons, which are supported solely by cross-phase modulation.
Using top-electrodes, we demonstrate the soliton-based miniaturized integration of electro-optic devices in a photorefractive paraelectric bulk crystal. Self-trapping and beam manipulation though soliton electro-activation is achieved at quasi-digital voltages.
We report on the propagation of high peak power higher-order solitons and their break up due to Raman scattering and third order dispersion over 30 m in hollow core photonic bandgap fibers.
Widely wavelength-tunable ultrashort pulses are generated using passively modelocked Yb-doped fiber laser and photonic crystal fiber. Soliton and anti-stokes pulses are generated in wavelength region of 1.0-1.7 mum and 0.6-0.7 mum, respectively.
Two-dimensional multicolored arrays of quadratic spatial solitons and up-converted parametric amplifications are observed through cascaded non-collinear quadratic processes in quadratic media, which can be switched by phase-insensitive weak beam control with second harmonic seeding pulses.
The recent progress on waves in nonlinear photonic lattices will be reviewed, with an emphasis on universal ideas that apply to all nonlinear periodic systems in which waves propagate.
Self-similar propagation in a system of coupled amplified nonlinear Schrodinger equations is studied. Each individual equation can sustain a component similariton and their incoherent summation leads to an incoherent parabolic similariton under a width-matching condition.
Formation of novel hybrid vector spatial plasmon-soliton in Kerr slab in-between metal plates is analyzed with a novel NLSE. The soliton self-trapping in lateral dimension is assisted by the plasmonic effect.
We observe experimentally nonlinear localization of beams in two-dimensional modulated Bessel-type photonic lattices with self-focusing nonlinear response.
A new method allows to extract information on soliton content in complicated cases of pulse propagation in optical fiber, not accessible to Inverse Scattering Transform. As an example, a dispersion-managed second order soliton is demonstrated.
It is theoretically shown that nonlinear surface-waves are possible in optical lattices. Such solitons can exist at the interface between two different semi-infinite 1D waveguide arrays and also at the boundaries of a 2D lattice.
In this paper, collapse dynamics of optical vortices, Laguerre-Gaussian modes are produced from 90-fs, 800-nm pulses of a Ti:Sapphire regenerative amplifier using spiral phase plates is investigated experimentally and theoretically. In the presence of azimuthal noise, we find that the beam breaks up into a highly predictable number of filaments as a function of power and topological charge.
We find a novel class of stable dissipative solitary waves with discrete velocities and few cycle temporal duration in a composite medium containing active and passive atoms.
We study soliton interactions in the highly-nonlocal thermal nonlinearity, demonstrating that solitons propagating in different samples, connected by metal-foils, attract one another. We demonstrate 3D-interactions between widely-separated solitons, which spiral about each other from afar.
Scattering of a dispersive wave on a soliton in a cobweb PCF resulting in generation of new spectral components is observed directly with XFROG technique. Recent analytical theory and numerical modeling confirm the results.
Detailed experimental investigations of the recently discovered temporal soliton molecules are reported. The optical fiber length was now extended; thus stable and unstable regimes of the soliton molecule can be distinguished from another more precisely.
We predict, in the framework of a nonlinear discrete model, and demonstrate experimentally in defocusing waveguide arrays, that self-localization near the edge of a photonic lattice can result in the formation of surface gap solitons.
We demonstrate that the soliton self-frequency shift can lead to dramatic reduction of group velocities of the initially fast pulses by shifting them into the near cut-off spectral regions of the structured waveguides.
