Modal formulation for diffraction by absorbing photonic crystal slabs
Kokou B. Dossou, Lindsay C. Botten, Ara A. Asatryan +5
A finite element-based modal formulation of diffraction of a plane wave by an absorbing photonic crystal slab of arbitrary geometry is developed for photovoltaic applications. The…
Optimizing Photovoltaic Charge Generation of Nanowire Arrays: A Simple Semi-Analytic Approach
Björn C. P. Sturmberg, Kokou B. Dossou, Lindsay C. Botten +4
Nanowire arrays exhibit efficient light coupling and strong light trapping, making them well suited to solar cell applications. The processes that contribute to their absorption ar…
Absorption enhancing proximity effects in aperiodic nanowire arrays
Björn C. P. Sturmberg, Kokou B. Dossou, Lindsay C. Botten +4
Aperiodic Nanowire (NW) arrays have higher absorption than equivalent periodic arrays, making them of interest for photovoltaic applications. An inevitable property of aperiodic ar…
Nanowire array photovoltaics: Radial disorder versus design for optimal efficiency
Björn C. P. Sturmberg, Kokou B. Dossou, Lindsay C. Botten +4
Solar cell designs based on disordered nanostructures tend to have higher efficiencies than structures with uniform absorbers, though the reason is poorly understood. To resolve th…
Anderson localization in metamaterials and other complex media
Sergey A. Gredeskul, Yuri S. Kivshar, Ara A. Asatrian +4
We review some recent (mostly ours) results on the Anderson localization of light and electron waves in complex disordered systems, including: (i) left-handed metamaterials, (ii) m…
Effects of polarization on the transmission and localization of classical waves in weakly scattering metamaterials
Ara A. Asatryan, Lindsay C. Botten, Michael A. Byrne +5
We summarize the results of our comprehensive analytical and numerical studies of the effects of polarization on the Anderson localization of classical waves in one-dimensional ran…
Modes of Random Lasers
Jonathan Andreasen, Ara Asatryan, Lc Botten +8
In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, ... In rand…
Random lasing in weakly scattering systems
X. Wu, W. Fang, A. Yamilov +4
We present detailed experimental and numerical studies of random lasing in weakly scattering systems. The interference of scattered light, which is weak in the passive systems, is…
