Inhibition of light emission in a 2.5D photonic structure
Romain Peretti, Christian Seassal, Pierre Viktorovich +1
We analyse inhibition of emission in a 2.5D photonic structures made up a photonic crystal (PhC) and Bragg mirrors using FDTD simulations. A comparison is made between an isolated…
Optical characterization of active photon cages
Rémy Artinyan, Aziz Benamrouche, Chérif Belacel +10
Recently, we developed a new family of 3D photonic hollow resonators which theoretically allow tight confinement of light in a fluid (gaz or liquid): the photon cages. These new re…
Absorption enhancement in photonic crystal thin films by pseudo disordered perturbations
Romain Peretti, Guillaume Gomard, Loïc Lalouat +2
The effects resulting from the introduction of a controlled perturbation in a single pattern membrane on its absorption are first studied and then analyzed on the basis of band fol…
Blue light absorption enhancement based on vertically channelling modes in nano-holes arrays
Guillaume Gomard, Romain Peretti, Ségolène Callard +6
We investigate the specific optical regime occurring at short wavelengths, in the high absorption regime, in silicon thin-films patterned by periodically arranged nano-holes. Near-…
Down Converter Device Combining Rare-Earth Doped Thin Layer and Photonic Crystal for c-Si Based Solar Cell
Thierry Deschamps, Emmanuel Drouard, Romain Peretti +7
The aim of the study is to develop ultra-compact structures enabling an efficient conversion of single high energy photon (UV) to two lower energy photons (IR). The proposed struct…
Absorption control in pseudodisordered photonic-crystal thin film
Romain Peretti, Guillaume Gomard, Loïc Lalouat +2
The positive effects of various perturbations introduced in a bidimensional photonic-crystal patterned membrane on its integrated absorption are investigated numerically and theore…
