Owing to its controllable tolerance, simple operation and no need for welding at construction site, the composite system involving grouted cement material, steel material and ductile iron material is widely used as grouted splice sleeve (GSS) connector for connecting precast concrete structures. However, the current design recommendations for such a composite connection system do not accurately...

We analyze nonlinear guided waves in a planar waveguide made of a left-handed material surrounded by a Kerr-like nonlinear dielectric, and predict that such a waveguide can support fast and slow symmetric and antisymmetric nonlinear modes. We study the symmetry breaking bifurcation and asymmetric modes in such a symmetric structure. The analysis of nonlinear dispersion properties of the guided ...

The organic nonlinear optical (NLO) material β-Alanine β-Alaninium Picrate (β-AAP) was grown by slow evaporation technique. Powder X-ray diffraction patterns were recorded and indexed for further confirmation of crystalline nature of grown (β-AAP) crystal. The transparent range of the grown material was studied using UV-Vis-NIR spectral analysis and the optical band gap was evaluated from the a...

Integrated optics platforms offer the possibility to implement compact photonic devices for nonlinear optics applications. Modern nanofabrication facilities allow the fabrication of sub-micron-sized waveguide geometries that confine light to reach very high optical intensities. These intensities enable efficient nonlinear processes that are further enhanced by using materials with high nonlinea...
