Demonstration of a cylindrically symmetric second-order nonlinear fiber with self-assembled organic surface layers.

چکیده
We report the fabrication and characterization of a cylindrically symmetric fiber structure that possesses significant and thermodynamically stable second-order nonlinearity. Such fiber structure is produced through nanoscale self-assembly of nonlinear molecules on a silica fiber taper and possesses full rotational symmetry. Despite its highly symmetric configuration, we observed significant second harmonic generation (SHG) and obtained good agreement between experimental results and theoretical predictions.

Self-assembled nanomaterials for nonlinear fiber optics and tunable plasmonics
As an amorphous material with full inversion symmetry, silica-based microstructures cannot possess significant secondorder nonlinearity. We recently developed a method that can potentially overcome this deficiency by coating a silica fiber taper with layers of radially aligned nonlinear molecules. The coating process can be accomplished through layerby-layer self-assembly, where the alignment o...
متن کاملModification of Copper with Self-assembled Thiol Monolayers
Self-assembled monolayers (SAM) make the creation of new types of protective layers possible, concerning corrosion, with which ecologically damaged procedures would be replaced for the protection of metal constructions from corrosion. Self-assembling is a spontaneous process which is developed by submerging of suitable metal substract into the melt with surface organic active substance, which i...
متن کاملCylindrically Symmetric Solitons with Nonlinear Self-gravitating Scalar Fields
Static, cylindrically symmetric solutions to nonlinear scalar-Einstein equations are considered. Regularity conditions on the symmetry axis and flat or string asymptotic conditions are formulated in order to select soliton-like solutions. Some non-existence theorems are proved, in particular, theorems asserting (i) the absence of black-hole and wormholelike cylindrically symmetric solutions for...
متن کاملNonlinear Dynamic Analysis of Pile Foundation Subjected to Strong Ground Motion Using Fiber Elements
In this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. In the created model, both pile and surrounding soil are modeled using fiber elements in a practical Beam on Nonlinear Winkler Foundation (BNWF) concept. Herein, the features of DRAIN–3DX finite element software are ...
