Novel Schiff base self-condensed oligomers in complexation with metallic triflates of low-band gap properties
(Springer-Verlag London Ltd, 2015)
Relationship between the optical gap and the optical-absorption tail breadth in amorphous GaAs
(American Institute of Physics (AIP), 2004-12-15)
We study the relationship between the optical gap and the optical-absorption tail breadth for the case of amorphous gallium arsenide (a-GaAs). In particular, we analyze the optical-absorption spectra corresponding to some ...

Surface multi-gap vector solitons
(Optical Society of American (OSA), 2006)
We analyze nonlinear collective effects near surfaces of semiinfinite periodic systems with multi-gap transmission spectra and introduce a novel concept of multi-gap surface solitons as mutually trapped surface states with ...
Microscopic theory of photonic band gaps in optical lattices
(Elsevier BVAmsterdam, 2014-02)
We propose a microscopic model to describe the scattering of light by atoms in optical lattices. The model is shown to efficiently capture Bragg scattering, spontaneous emission and photonic band gaps. A connection to the ...
Thermal tunability of photonic bandgaps in photonic crystal fibers selectively filled with nematic liquid crystal
(2010-12-01)
We address the bandgap effect and the thermo-optical response of high-index liquid crystal (LC) infiltrated in photonic crystal fibers (PCF) and in hybrid photonic crystal fibers (HPCF). The PCF and HPCF consist of solid-core ...

Microstructure, dielectric properties and optical band gap control on the photoluminescence behavior of Ba[Zr0.25Ti0.75]O-3 thin films
(Springer, 2009-01-01)
Ba[Zr0.25Ti0.75]O-3 (BZT) thin films were synthesized by the complex polymerization method and heat treated at 400 A degrees C for different times and at 700 A degrees C for 2 h. These thin films were analyzed by X-ray ...
