Multiplexing photons with a binary division strategy
We present a scheme to produce clock-synchronized photons from a single parametric downconversion source with a binary division strategy. The time difference between a clock and detections of the herald photons determines ...
Inverse Opal Photonic Crystals as a Strategy to Improve Photocatalysis: Underexplored Questions
(American Chemical Society, 2015-10)
The structuring of materials in the form of photonic crystals for photocatalytic applications is a quite new strategy aiming to enhance the performance of the photocatalysts at wavelength ranges where their absorption is ...

Chemical two-photon fluorescence
(American Chemical Society, 2015-04)
We describe a method based on a caged fluorescent molecule that can act as a chemical two-photon probe. It is composed of an organic fluorophore and a ruthenium-bipyridine complex that acts as a photoremovable quencher. ...
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 ...

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 ...
