Journal ArticleDOI
Two-dimensional steady-state photorefractive screening solitons.
TL;DR: The solitons are observed to be axially symmetric, and they self-bend, and the soliton dependence on the optical intensity, applied electric-field strength, and beam diameter is characterized.
Journal ArticleDOI
Three-Dimensional Spiraling of Interacting Spatial Solitons
TL;DR: In this paper, a three-dimensional spiraling collision of interacting two-dimensional spatial solitons is observed, where the collision provides the soliton with angular momentum which is manifested in a centrifugal repulsion force.
Journal ArticleDOI
Laser Ablated Carbon Nanodots for Light Emission
Delfino Reyes,Delfino Reyes,Marco Camacho,Miguel Camacho,M. Mayorga,Duncan L. Weathers,Greg Salamo,Zhiming Wang,Arup Neogi +8 more
TL;DR: The synthesis of fluorescent carbon dots-like nanostructures (CNDs) obtained through the laser ablation of a carbon solid target in liquid environment is reported and the light emission from the CNDs is most efficient due to ablation at 355 nm.
Journal ArticleDOI
One-dimensional Steady-State Photorefractive Screening Solitons
TL;DR: One-dimensional steady-state photorefractive screening solitons in a bulk strontium barium niobate crystal are stable against perturbations both in the plane and perpendicular to the plane of the soliton.
Journal ArticleDOI
Self-trapping of planar optical beams by use of the photorefractive effect in InP:Fe
TL;DR: It is shown that the observed focusing and defocusing effects follow the component of the two-wave-mixing space charge field that is in phase with the intensity pattern, whereas the spatial beam deflection effects following the 90 degrees -shifted component.
