Significant enhancement of the optical second harmonic generation in a poled azopolymer thin grating
Article Abstract:
The nonlinear optical properties of an electronically poled surface relief grating (SRG) inscribed on a thin film of azopolymer are analyzed. A drastic enhancement of second harmonic generation (SHG) from a poled SRG inscribed on an azobenzene-containing polymer thin film is noticed when the phase and the angular matching conditions are fulfilled.

Synthesis of TiO2/SiO2 core/shell nanocable arrays
Article Abstract:
The morphology, microstructure and chemical composition of the nanocables are characterized by using scanning electron microscopy, transmission electron microscopy and spatial resolution energy depressive X-ray spectroscopy. A possible growth mechanism of the nanocables is proposed on the basis of thermodynamic and kinetic considerations.
