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…
Large field enhancement obtained by combining Fabry-Perot resonance and Rayleigh anomaly in photonic crystal slabs
Kokou B. Dossou
By applying the properties of Fabry-Perot resonance and Rayleigh anomaly, we have shown that a photonic crystal slab can scatter the light from an incident plane wave into a diffra…
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…
Doppler shift generated by a moving diffraction grating under incidence by polychromatic diffuse light
Kokou B. Dossou
We consider the spectral response of moving diffraction gratings, in which the incident light extends over a broad angular range and where the diffracted light is observed from a s…
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…
Doppler shift generated by diffraction gratings under time-dependent incidence angle near a Wood anomaly
Kokou B. Dossou
Diffraction gratings are famous for their ability to exhibit, near a Wood anomaly, an arbitrarily large angular dispersion, e.g., with respect to the incidence angle or wavelength.…
