NumBAT: The integrated, open source Numerical Brillouin Analysis Tool
Björn C. P. Sturmberg, Kokou B. Dossou, Michael J. A. Smith +3
We describe NumBAT, an open-source software tool for modelling stimulated Brillouin scattering in waveguides of arbitrary cross-section. It provides rapid calculation of optical an…

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…

Total absorption of visible light in ultra-thin weakly-absorbing semiconductor gratings
Björn C. P. Sturmberg, Teck K. Chong, Duk-Yong Choi +7
The perfect absorption of light in subwavelength thickness layers generally relies on exotic materials, metamaterials or thick metallic gratings. Here we demonstrate that total lig…
