TLDR
In this article, the first experimental observation of higher-order modes guided by soliton-induced waveguides in nematic liquid crystals was reported. But the results were limited to a bounded power region specific to each guided mode.Abstract:
We report on the first (to our knowledge) experimental observation of higher-order modes guided by soliton-induced waveguides in nematic liquid crystals. We find that the nematicon waveguides operate in a bounded power region specific to each guided mode. Below this region, the guided beams diffract; above this region, the mode mixing and coupling give rise to an unstable output.read more

Dipole azimuthons and vortex charge flipping in nematic liquid crystals.
TL;DR: Self-trapped laser beams carrying phase singularities in nematic liquid crystals are demonstrated and the astigmatic transformation of vortex beams into spiraling dipole azimuthons accompanied by power-dependent charge-flipping of the on-axis phase singularity is observed.

Observation of stable-vector vortex solitons
TL;DR: This report reports on the first experimental observation of stable-vector vortex solitons in nonlocal nonlinear media with a reorientational response, such as nematic liquid crystals, as well as a bright fundamental spatial soliton in a nonlinear optical vortex.

High-order revivable complex-valued hyperbolic-sine-Gaussian solitons and breathers in nonlinear media with a spatial nonlocality
TL;DR: In this paper, the evolution of complex-valued hyperbolic-sine-Gaussian beams (CVHSGBs) is investigated in nonlinear media with a spatial nonlocality.

Tripole-mode and quadrupole-mode solitons in (1 + 1)-dimensional nonlinear media with a spatial exponential-decay nonlocality
TL;DR: It is found that the soliton powers for the two types of solitons are not equal with the same parameters, which is much different from their counterparts in the Snyder-Mitchell model.

Optical solitons : from fibers to photonic crystals
TL;DR: In this article, the authors introduce spatial and temporal solitons in photonic crystals, and introduce the concept of Incoherent Solitons, which is a subclass of the spatial and temporally soliton.

Observation of optical spatial solitons in a highly nonlocal medium.
TL;DR: The observations and quantitative assessment of self-trapped pulsating beams in a highly nonlocal nonlinear regime allow a meaningful comparison with the prediction of a scalar theory in the perturbative limit, while addressing the need for beyond-paraxial analytical treatments.

Electrically assisted self-confinement and waveguiding in planar nematic liquid crystal cells
TL;DR: In this article, spatial soliton formation and self/cross waveguiding in planar cells containing a nematic liquid crystal in the presence of an externally applied voltage were demonstrated with an Argon ion laser (514 nm) and a helium-neon probe (633 nm) over millimeter lengths and with milliwatt pump powers.

Cell biology: Explorers deliver tea to the pole
TL;DR: New work indicates that a protein called tea1 acts as a marker, to direct the cellular growth machinery to the poles, and is localized to, and maintained at, the poles by the microtubular cytoskeleton.
