Anomalous group velocity at the high energy range of a 3D photonic nanostructure
(Optical Society of America, 2010-07)
We report on a study of electromagnetic waves propagation in thin periodically ordered photonic nanostructures in the spectral range where the light wavelength is on the order of the lattice parameter. The vector KKR method ...
Computing Optical Properties of Photonic Crystals by Using Multilayer Perceptron and Extreme Learning Machine
In this paper, dispersion relations (DRs) of photonic crystals (PhCs) are computed by multilayer perceptron (MLP) and extreme learning machine (ELM) artificial neural networks (ANNs). Bi- and tri-dimensional optimized ...
Refractive index effect in the lattice geometry of photonic crystals generated by multi-exposure interference patterns

PHOTON MASS and VERY LONG BASELINE INTERFEROMETRY
(World Scientific Publ Co Pte Ltd, 2010-12-01)
A relation between the photon mass, its frequency, nu, and the deflection parameter, gamma, determined by experimentalists (that characterizes the contribution of space curvature to gravitational deflection) is found. This ...
Determination of the Θ+ parity from γn → K -K+n
It is demonstrated that measurements of photon asymmetry in the γn → K-K+n reaction, can most likely determine the parity of the newly discovered Θ+ pentaquark. We predict that if the parity of Θ+ is positive, the photon ...
Recent developments in chalcogenide photonic crystal fibres
Elaboration of low-losses highly non linear chalcogenide optical fibers for the generation of efficient non linear effects in the infrared remains a challenge. In recent years, much work has been devoted to the study of ...
Enhancement of Atom-Field Transfer of Coherence in a Two-Photon Micromaser Assisted by a Classical Field
(Natural Sciences Publishing Corp-nspNew YorkEUA, 2014)
Band-edge states of the zero(th)-order gap in quasi-periodic photonic superlattices
(Spie - Int Soc Optical Engineering, 2008-01-01)
The photonic modes of Thue-Morse and Fibonacci lattices with generating layers A and B, of positive and negative indices of refraction, are calculated by the transfer-matrix technique. For Thue-Morse lattices, as well for ...
